CD18, integrin beta2 subunit, forms heterodimers with four types of CD11 molecule to constitute leukocyte (beta2) integrins: alphaLbeta2 (CD11a/CD18, LFA-1), alphaMbeta2 (CD11b/CD18, Mac-1, CR3), alphaXbeta2 (CD11c/CD18) and alphaDbeta2 (CD11d/CD18). In most cases, the response mediated by the integrin is a composite of the functions of its individual subunits. These integrins are essential for proper leukocyte migration, mediating intercellular contacts. Absence of CD18 leads to leukocyte adhesion deficiency-1; severe reduction of CD18 expression leads to the development of a psoriasiform skin disease. CD18 is also a target of Mannheimia (Pasteurella) haemolytica leukotoxin and is sufficient to mediate leukotoxin-mediated cytolysis.SpecificityThe mouse monoclonal antibody G28-8 recognizes an extracellular epitope of CD180, a 95-105 kDa TLR-like glycoprotein expressed on peripheral blood monocytes and dendritic cells, mantle zone B cells and marginal zone B cells, but very weakly on germinal center B cells.Application detailsWestern blotting: Recommended dilution: 2 ?g/ml; positive control: Kg-1a human leukemia cell lysate, non-reducing conditions. <br>Flow cytometry: Recommended dilution: 2 ?g/ml. <br>Immunohistochemistry (paraffin sections): Recommended dilution: 10 ?g/ml; positive tissue: spleen, microglia.

The Biosensis proBDNF Rapid TM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the specific, fast and reliable quantification of proBDNF in less than 4 hours in cell culture supernatants, human serum and EDTA-plasma only if used as directed. Please refer to the kit protocol for specific use instructions for each substrate application, in particular human blood samples. This ELISA kit consists of a pre-coated monoclonal anti-proBDNF capture antibody, a biotinylated anti-matureBDNF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a colored reaction product which is directly proportional to the concentration of proBDNF present in samples and protein standards. A proBDNF positive control (QC sample) is provided to assure consistent assay performance. This proBDNF ELISA kit employs a recombinant, cleavage-resistant human proBDNF standard produced in mammalian cells by Biosensis and validated against externally available proBDNF proteins. Note that accurate proBDNF quantification in human serum and EDTA-plasma requires the addition of Heterophilic Antibody Blocker BL-004-500 provided in the kit, and available for purchase separately . This ELISA kit has not been tested for other applications. It has been configured for research use only and is not to be used for diagnostic or clinical procedures.
Background Info:
BDNF belongs to the neurotrophin family and regulates the survival and differentiation of neurons during development. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. FUNCTION: Promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. Major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. Post Translation Modification (PTM): The propeptide is N-glycosylated and glycosulfated. PTM: Converted into mature BDNF by plasmin (PLG) (By similarity). DISEASE: Defects in BDNF are a cause of congenital central hypoventilation syndrome (CCHS); also known as congenital failure of autonomic control or Ondine curse. CCHS is a rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia. CCHS is frequently complicated with neurocristopathies such as Hirschsprung disease that occurs in about 16% of CCHS cases. SIMILARITY: Belongs to the NGF-beta family.

The Biosensis Mature BDNF Rapid TM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of mature BDNF in less than 3 hours in cell culture supernatants, serum, plasma (citrate and EDTA), pig serum, cell lysates, brain extracts, human milk and Sheep CSF only if used as directed, with a simplified protocol and no loss of sensitivity or specificity. Please refer to the kit protocol for specific use instructions for each substrate application, in particular blood samples, human milk and CSF. Note that accurate quantification of BDNF in human milk requires a secretory IgA (sIgA) blocker which can be purchased separately ( BL-001-1250 ). For measurement of mature BDNF in CSF samples, please contact us at sales@biosensis.com . This ELISA kit has been tested in independent research laboratories and found to achieve highest reproducibility with intra- and inter-assay CVs as low as 1% and 5%, respectively (Polacchini et al., 2015). This ELISA kit consists of a pre-coated mouse monoclonal anti-mature BDNF capture antibody, a biotinylated anti-mature BDNF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a coloured reaction product which is directly proportional to the concentration of mature BDNF present in samples and protein standards. A BDNF positive control (QC sample) is provided to assure consistent assay performance. This Mature BDNF ELISA kit employs a recombinant human mature BDNF standard approved by the World Health Organization (WHO, www.nibsc.org ). The amino acid sequence of mature BDNF is identical for human, mouse, rat and a number of other species. This kit therefore is suitable to measure mature BDNF in all these species and uses the same antibodies and antigen. Extensive validation has demonstrated that the Mature BDNF Rapid TM ELISA shows only minimal cross-reactivity with proBDNF. Please refer to our Technical Note #5 for further details on ELISA assay validation for BDNF isoform detection and quanification. This ELISA kit has not been tested for other applications. It has been configured for research use only and is not to be used for diagnostic or clinical procedures. For in-vitro diagnostic (IVD) applications in the European Economic Area (EEA), we refer to the CE Marked BDNF ELISA kit (BEK-2211-CE) .

Typical limit of detection (LOD) for BDNF is less than 2 pg/mL, determined as 150% of the blank value.
Cross Reactivity:
No cross-reactivity is observed for nerve growth factor (NGF), neurotrophin-3 (NT-3), NT-4/5, glial cell line-derived neurotrophic factor (GDNF) and vascular endothelial growth factor (VEGF165) tested at 25 ng/mL in assay buffer. The reactivity of full-length proBDNF (0.125 ng/mL - 5 ng/mL) was determined in six independent assays using proBDNF proteins from four different sources (mammalian and bacterial, wild-type and mutated). The average cross-reactivity of proBDNF was found to be 5.3% +/- 0.5% in weight (w/v) concentration, or 12.1% +/- 1.2% in molar concentration (mean +/- SEM). Additional proBDNF cross-reactivity experiments were conducted as summarized in our <a class="newA" target="_blank" href="https://www.biosensis.com/documents/enhancedinfo/Technical-Note-5-Mature-BDNF-Isoform-Detection-and-Quantification-by-ELISA.pdf">Technical Note #5</a>.
The Biosensis Mature BDNF Rapid TM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of mature BDNF in less than 3 hours in cell culture supernatants, serum, plasma (citrate and EDTA), pig serum, cell lysates, brain extracts, human milk and Sheep CSF only if used as directed, with a simplified protocol and no loss of sensitivity or specificity. Please refer to the kit protocol for specific use instructions for each substrate application, in particular blood samples, human milk and CSF. Note that accurate quantification of BDNF in human milk requires a secretory IgA (sIgA) blocker which can be purchased separately ( BL-001-1250 ). For measurement of mature BDNF in CSF samples, please contact us at sales@biosensis.com . This ELISA kit has been tested in independent research laboratories and found to achieve highest reproducibility with intra- and inter-assay CVs as low as 1% and 5%, respectively (Polacchini et al., 2015). This ELISA kit consists of a pre-coated mouse monoclonal anti-mature BDNF capture antibody, a biotinylated anti-mature BDNF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a coloured reaction product which is directly proportional to the concentration of mature BDNF present in samples and protein standards. A BDNF positive control (QC sample) is provided to assure consistent assay performance. This Mature BDNF ELISA kit employs a recombinant human mature BDNF standard approved by the World Health Organization (WHO, www.nibsc.org ). The amino acid sequence of mature BDNF is identical for human, mouse, rat and a number of other species. This kit therefore is suitable to measure mature BDNF in all these species and uses the same antibodies and antigen. Extensive validation has demonstrated that the Mature BDNF Rapid TM ELISA shows only minimal cross-reactivity with proBDNF. Please refer to our Technical Note #5 for further details on ELISA assay validation for BDNF isoform detection and quanification. This ELISA kit has not been tested for other applications. It has been configured for research use only and is not to be used for diagnostic or clinical procedures. For in-vitro diagnostic (IVD) applications in the European Economic Area (EEA), we refer to the CE Marked BDNF ELISA kit (BEK-2211-CE) .
Background Info:
BDNF belongs to the neurotrophin family and regulates the survival and differentiation of neurons during development. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. FUNCTION: Promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. Major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. Post Translation Modification (PTM): The propeptide is N-glycosylated and glycosulfated. PTM: Converted into mature BDNF by plasmin (PLG) (By similarity). DISEASE: Defects in BDNF are a cause of congenital central hypoventilation syndrome (CCHS); also known as congenital failure of autonomic control or Ondine curse. CCHS is a rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia. CCHS is frequently complicated with neurocristopathies such as Hirschsprung disease that occurs in about 16% of CCHS cases. SIMILARITY: Belongs to the NGF-beta family.

CD3 complex is crucial in transducing antigen-recognition signals into the cytoplasm of T cells and in regulating the cell surface expression of the TCR complex. T cell activation through the antigen receptor (TCR) involves the cytoplasmic tails of the CD3 subunits CD3 gamma, CD3 delta, CD3 epsilon and CD3 zeta. These CD3 subunits are structurally related members of the immunoglobulins super family encoded by closely linked genes on human chromosome 11. The CD3 components have long cytoplasmic tails that associate with cytoplasmic signal transduction molecules. This association is mediated at least in part by a double tyrosine-based motif present in a single copy in the CD3 subunits. CD3 may play a role in TCR-induced growth arrest, cell survival and proliferation._x000D_ The CD3 antigen is present on 68-82% of normal peripheral blood lymphocytes, 65-85% of thymocytes and Purkinje cells in the cerebellum. It is never expressed on B or NK cells. Decreased percentages of T lymphocytes may be observed in some autoimmune diseases.

CD180, also known as RP105 (or Bgp95, LY64) is a type I membrane glycoprotein of Toll-like receptor (TLR) family. Its cytoplasmic tail is short and unlike the TLRs, it lacks the TIR domain. CD180 expression is dependent on the coexpression of its helper molecule, MD-1, and mirrors that of TLR4 on antigen-presenting cells. CD180 regulates recognition of LPS and signaling in B cells, via interacting directly with the TLR4 signaling complex, inhibiting its ability to bind microbial ligands. Ligation of CD180 by monoclonal antibodies leads to B cell activation, upregulation of CD80/CD86, and increase in cell size.

The mouse monoclonal antibody G28-8 recognizes an extracellular epitope of CD180, a 95-105 kDa TLR-like glycoprotein expressed on peripheral blood monocytes and dendritic cells, mantle zone B cells and marginal zone B cells, but very weakly on germinal center B cells.
CD180, also known as RP105 (or Bgp95, LY64) is a type I membrane glycoprotein of Toll-like receptor (TLR) family. Its cytoplasmic tail is short and unlike the TLRs, it lacks the TIR domain. CD180 expression is dependent on the coexpression of its helper molecule, MD-1, and mirrors that of TLR4 on antigen-presenting cells. CD180 regulates recognition of LPS and signaling in B cells, via interacting directly with the TLR4 signaling complex, inhibiting its ability to bind microbial ligands. Ligation of CD180 by monoclonal antibodies leads to B cell activation, upregulation of CD80/CD86, and increase in cell size.
