Affinity Biosciences - Research Together


Affinity Biosciences is a provider of innovative tools for signal transduction research with a focus on well validated phospho-specific antibodies.


Use our search to find your antibody (e.g. Ser724, IRE1 or Phospho-IRE1 etc).


Well Validated Phospho-specific Antibodies

Validation is important for any antibody, but for Phospho-specific antibodies it is even more important as specificity is truly key to their use.


Affinity antibody validation begins with Mass Spec (MS) analysis of the blocking peptide to ensure the peptide sequence is accurate, followed by checking that the antibody and the blocking peptide correspond correctly, with the peptide blocking the antibody in Western Blotting of research samples showing blocking and control lanes without the peptide to show binding of the target.


Images are provided on the datasheets of Western blots and use in other applications such as Immunohistochemistry as appropriate.


As an example, details of the validation of our Phospho-IRE1 (Ser724) - AF7150 antibody have been provided below:

Optibodies from Nordic Biosite


You have most likely been using antibodies in Immunohistochemistry for some time and maybe you are getting good results, but Optibodies are on another level.


In producing the Optibodies range we ensure that every antibody provides beautifully optimised staining. This is the key aim of the Optibodies range and any antibody that does not perform to this standard simply does not make it in to the range.


Optibody™ optimisation involves a great number of tests in order to find the optimal staining conditions.


Antigen Retrieval

Each antigen has a preferred method of antigen retrieval such as heat induced epitope retrieval using citrate buffer, as well as an enzymatic retrieval process, but the majority of antigens need alkaline antigen retrieval conditions for truly optimal staining. For this reason, Optibodies are all selected according to the performance in alkaline antigen retrieval.



Antibodies generally have an optimal concentration for use, depending on the affinity of the antibody for its target and expression level of the antigen. Antibodies optimised with tissues expressing high levels of antigen may prove inadequate when staining tissues with low antigen expression. So Optibodies are optimised on a variety of tissue types and antigen expression levels to verify the performance of the Optibody in a range of situations.


Internal and External QC

To ensure the high quality of every Optibody, as well as our own high level of internal quality control, we also take part in external quality assurance programs to ensure our antibodies work optimally in the hands of others too.


Other key criteria

Another key target for each Optibody is specificity and high affinity towards the target. They are also tailored to be flexible and reliable in use, with high consistency between lots and excellent stability.


More information on the full Optibodies range is available on this link.

Extracellular Vesicles (EVs), including exosomes, express antigens with 3D conformations and/or post-translational modifications that often differ from the cellular counterpart. For this reason, most of the antibodies currently available on the market fail to recognise exosome-associated antigens with sufficient sensitivity and specificity.


In collaboration with Exosomics Siena Spa, HansaBioMed has validated a set of polyclonal and monoclonal antibodies against common exosomal markers (CD63, CD81, ALIX) and disease-specific exosomal markers (cancer and neurodegenerative diseases) as listed below.

The ImmunoStar range of antibodies for neuroscience research are put through extensive testing before release to ensure both high quality and high titer. This provides excellent reliability and lot-to-lot consistency. The antibodies have also been specifically tested for use in immunohistochemistry.


This range of primary antibodies was originally provided by DiaSorin (formerly INCSTAR), but in 2001 the range became Immunostar. As these antibodies have been available for many years, there are multiple references citing their use.



Details of the full range of 60+ well referenced neuroscience antibodies are available on this link.


NS Reagents - Featured Antibodies


Anti-TDP43 (Clone DB9)


TAR DNA-binding protein 43 (TDP-43) has been shown to bind both DNA and RNA and have multiple functions in transcriptional repression, pre-mRNA splicing and translational regulation. It belongs to the hnRNP protein family and is highly expressed in the pancreas, placenta, lung, genital tract and spleen. Characterisation of transcriptome-wide binding sites revealed that thousands of RNAs are bound by TDP-43 in neurons.


TDP-43 regulates alternate splicing of the CFTR gene. The resulting aberrant splicing is associated with pathological features typical of cystic fibrosis. Mutations in TDP-43 have been associated with amyotrophic lateral sclerosis, frontotemporal dementia, Parkinson's disease and Alzheimer's disease.


Applications: ELISA ¦ IHC ¦ WB         Host: Mouse      Reactivity: Human



Anti-DNA damage-binding protein 1


DNA damage-binding protein 1 (DDB1) is the large subunit (p127) of the heterodimeric DNA damage-binding (DDB) complex. DDB1 also functions as a core component of the cullin 4 (CUL4) ubiquitin E3 ligase complex, facilitating the binding of substrates to this complex and the ubiquitination of proteins. These factors (ubiquitin ligase substrates) regulate numerous essential processes in the cell including DNA repair (DDB2), DNA replication, chromatin remodelling (Cdt2) and more.


Applications: WB           Host: Rabbit      Reactivity: Human

Mouse anti Human Granzyme B, clone GrB-7 This antibody reacts with the 33 kD human serine protease granzyme B. It does not cross react with human granzyme A. It can be used as a marker for NK-cells and activated cytotoxic T-cells (CTL).


This monoclonal antibody stains granzyme B expressing lymphocytes in sections of sublimate formaldehyde as well as formalin fixed paraffin embedded tissues. It does not react with other cell types. The antibody can not be used on frozen sections. The antibody is also useful for staining granzyme B protein on Western blots.


Granzyme B staining 


Mouse anti Human Desmin, clone D33 This antibody is highly reactive with desmin and does not cross react with GFAP, Keratin, Vimentin or Neurofilament. This antibody stains muscle cells in human tissues. Frozen sections show excellent staining in immunohistochemistry or immunofluorescence. On sections of formalin fixed and paraffin embedded tissue the staining is reduced. This antibody is also useful in Western blots.


Desmin staining


Mouse anti CD56, Neural Cell Adhesion Molecule, NCAM, clone 123C3 This antibody recognizes a transmembrane glycoprotein of 140 and 180 kD which has been identified as NCAM (Neural Cell Adhesion Module). It reacts with epitope 2 of the two major epitopes which have been defined for NCAM. Thsi antibody is primarily used for the study of small cell carcinoma. Detection of CD56 positive lymphomas.


At the international Workshop on SCLC antibodies this clone was categorised as cluster 1 antibody (Stahel et al 1994). Most importantly, Clone 123C3 can be used on routing formalin fixed paraffin sections after retrieval and it stains all cells in small cell carcinomas and carcinoids of the lung strongly positive. Neuroblastoma's, wilms tumors and adenoid cystic carcinomas of bronchial glands are also stained strongly positive.


In non small lung cell carcinomas, clone 123C3 staining has been associated with more advanced stage and a decreased survival after surgery (Kibbelaar et al. 1991). Positive staining with other tumors, include medullary thyroid carcinomas and some ovarian tumors. NCAM (CD56) is a marker for natural killer cells and clone 123C3 can be used to distinguish NK cells from other haematopoietic cell populations. 


SCC Lung CD56


Mouse anti Keratin 7, clone OVTL12/30 This antibody reacts specifically with Keratin 7. It stains a 54 kD protein band of cytoskeletal proteins from cell lines in one and two dimensional immuno blots. It cross reacts with human and mouse. The antibody is a useful marker for histopathology and can be used to distinguish between ovarian carcinomas and colon carcinomas in paraffin embedded tissue sections.


 CK 7 Staining


Mouse anti Eosinophil Major Basic Protein, clone BMK-13 This antibody binds to the 10 kD eosinophil Major Basic Protein (MBP) of both resting and activated eosinophils in cytospins and frozen sections of bronchial and skin biopsies of allergic sites and normal sites and thus can be used as a "pan - eosinophil" marker. It stains frozen sections of bronchial biopsies from atopic asthmatics, rhinitics and normal non-atopic subjects. It does not cross - react with any other human protein or cell.


This mAb is a very useful tool for clinical and experimental allergy studies. Clone BMK-13 is a pan-eosinophil marker in both frozen sections and paraffin embedded tissues. Also this antibody can be used in specific ELISA tests to determine the release of MBP and to quantify the number of eosinophils in various in vitro adhesion assays.


Breast Cancer Drug Resistance Antibodies 


Tumour cell insensitivity to anticancer drugs frequently appears as multidrug resistance (MDR), associated with the overexpression of one or more of a set of at least 10 different molecules, causing reduced drug levels at the intracellular target sites. These overexpressed molecules include transmembrane transporter proteins such as P glycoprotein, MRP1-9 and BCRP. In addition, the lung-resistance protein, recently identified as the major vault protein, has also been associated with MDR.

Our Monosan monoclonal antibodies specifically recognise these proteins and so can be used to help identify their roles in clinical drug resistance and explore their occurrence in normal human tissues and physiology. 


We highlight 4 of our Multi Drug Resistance Antibodies below, followed by a list all of the available antibodies in our Multi Drug Resistance range.


Anti Breast Cancer Resistance Protein (ABCG2) Clone BXP-21. This monoclonal antibody reacts with an internal epitope of BCRP, a 70 kD transmembrane half-transporter which is involved in Multidrug resistance. BXP-21 did not cross-react with the human MDR1, MRP1or MRP2 gene products during testing.


BXP21_VUMC 1_200_200x


Anti MDR3 P-gp (ABCB4) Clone P3II-26. This monoclonal antibody reacts with an internal epitope of MDR3 P-gp (a fragment of MDR3 P-gp comprising amino acid 629 - 692). P3II-26 does not cross-react with human MDR1 P-gp.


Anti MRP2 (ABCC2) Clone M2III-6. This monoclonal antibody reacts with an internal epitope of cMOAT/MRP2, a 170-180 kD transmembrane protein known as the canalicular multi-organic anion transporter, absent in patients with the Dubin-Johnson syndrome, an autosomal recessive liver disorder characterised by chronic conjugated hyperbilirubinemia. cMOAT/MRP2 is closely related to the multidrug resistance related protein MRP, and its overexpression has been observed in a subset of cisplatin resistant cell lines. Clone M2III-6 did not cross react with the human MDR1, MRP1, MRP3 and MRP5 gene products.
