Invitrogen™ TCR V beta 10b Monoclonal Antibody (B21.5), Biotin, eBioscience™, Invitrogen™

Beskrivning

Description: The B21.5 monoclonal antibody reacts with the Vbeta10 T Cell Receptor (TCR) in mice of the b haplotype of the TCR Vbeta gene complex, which includes AKR, BALB/c, CBA, C3H/He, C57BL, DBA/1 and DBA/2 mice. It does not react with Vbeta10 in mice of the a or c haplotypes of the TCR Vbeta gene complex, including C57BR, C57L, SJL, and SWR mice. Applications Reported: This B21.5 antibody has been reported for use in flow cytometric analysis. Applications Tested: This B21.5 antibody has been tested by flow cytometric analysis of C57Bl/6 mouse splenocytes. This can be used at less than or equal to 0.25 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Filtration: 0.2 μm post-manufacturing filtered.

The ability of T cell receptors (TCR) to discriminate foreign from self-peptides presented by major histocompatibility complex (MHC) class II molecules is essential for an effective adaptive immune response. TCR recognition of self-peptides has been linked to autoimmune disease. Mutant self-peptides have been associated with tumors. Engagement of TCRs by a family of bacterial toxins know as superantigens has been responsible for toxic shock syndrome. Autoantibodies to V beta segments of T cell receptors have been isolated from patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). The autoantibodies block TH1-mediated inflammatory autodestructive reactions and are believed to be a method by which the immune system compensates for disease (ref5). T Cell and TCR Diversity Most human T cells express the TCR alpha-beta and either CD4 or CD8 molecule (single positive, SP). A small number of T cells lack both CD4 and CD8 (double negative, DN). Increased percentages of alpha-beta DN T cells have been identified in some autoimmune and immunodeficiency disorders. Gamma-delta T cells are primarily found within the epithelium. They show less TCR diversity and recognize antigens differently than alpha-beta T cells. Subsets of gamma-delta T cells have shown antitumor and immunoregulatory activity.
