Invitrogen™ TCR V beta 12 Monoclonal Antibody (MR11-1), PerCP-eFluor™ 710, eBioscience™

Mouse Monoclonal Antibody

Supplier:  Invitrogen™ 46579880

Catalog No. 50-245-917

Description

Description: This MR11-1 monoclonal antibody reacts with the mouse T cell receptor (TCR) V beta 12 chain. Composed of an alpha and beta chain, TCR specificity is typically determined by Va, Ja, Vb, Db, and Jb gene rearrangement. The MR11-1 antibody recognizes the V beta 12 chain on T cells from mouse strains with the b haplotype, including C57BL/6, B10, and C58/J. V beta 12+ T cells are absent in strains with the a (e.g., SJL) or c (e.g., RIII) haplotypes of the Tcrb gene complex. Finally, mouse strains expressing the minor lymphocyte stimulatory (Mls) antigens, such as BALB/c and C3H, express fewer V beta 12+ T cells. Applications Reported: This MR11-1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This MR11-1 antibody has been tested by flow cytometric analysis of mouse lymph node. 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. PerCP-eFluor® 710 can be used in place of PE-Cy5, PE-Cy5.5 or PerCP-Cy5.5. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm). Please make sure that your instrument is capable of detecting this fluorochrome. For a filter configuration, we recommend using ...

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.
