CD27 is a transmembrane 55 kDa protein of the nerve growth factor-receptor family, expressed as a disulfide-linked homodimer on mature thymocytes, peripheral blood T cells and a subpopulation of B cells. Activation of T cells via TCR-CD3 complex results in upregulation of CD27 expression on the plasma membrane as well as in the release of its soluble 28-32 kDa form, sCD27, detected in the plasma, urine or spinal fluid. This sCD27 is an important prognostic marker of acute and chronic B cell malignancies. RgpA, a cystein proteinase, although activating T cells through the protease-activated receptors (PARs), degradates CD27 and counteracts T cell activation mediated by CD27 and its ligand CD70.

Application Details:
Flow cytometry: The reagent is designed for analysis of human blood cells using 10 ?l reagent / 100 ?l of whole blood or 106 cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.
The 5-HT 2C Receptor Antibody was raised against synthetic peptide sequence corresponding to amino acids 439-460 of the rat 5-HT2C receptor coupled to KLH and bovine thyroglobulin. The ImmunoStar 5-HT2C receptor antiserum was quality control tested using standard immunohistochemical methods. The antiserum demonstrates strongly positive labeling of rat choroid plexus and hippocampus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilutions are /500 - 1/1000 in PBS - Bn/Av-HRP technique. Intensification methods such as nickel will approximately double the dilution factor as recommended. The antibody was characterized by immunohistochemistry and Western blot. Western blotting revealed a single band of approximately 70 kD. Preincubation of the antibody with an excess of the synthetic peptide blocked staining. Immunohistochemical staining of rat brain correlates well with Northern analysis, in situ hybridization and receptor autoradiography. BlastP database sequence homology searches confirmed that this sequence is unique to rat, mouse and human 5-HT2C receptors.
