Description

Mouse Monoclonal Antibody

Description: This MR9-4 monoclonal antibody reacts with the mouse T cell receptor (TCR) V beta 5.1/5.2 chain. Composed of an alpha and beta chain, TCR specificity is typically determined by Va, Ja, Vb, Db, and Jb gene rearrangement. The MR9-4 antibody recognizes the V beta 5.1 and 5.2 chains on T cells from mouse strains with the b haplotype of the Tcrb gene, including C57BL/6, B10, and C58/J. V beta 5.1 and 5.2 are deleted in mouse strains that express MHC Class II I-E, including Balb/c, C3H, and DBA/2. Reports also indicate that V beta 5+ T cells recognize the OVA peptide. Applications Reported: This MR9-4 antibody has been reported for use in flow cytometric analysis. Applications Tested: This MR9-4 antibody has been tested by flow cytometric analysis of mouse splenocytes. This may be used at less than or equal to 1 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. Alexa Fluor 700 emits at 723 nm and can be excited with the red laser (633-647 nm). Most instruments will require a 685 LP mirror and 710/20 band pass filter. Please make sure that your instrument is capable of detecting this fluorochrome. Excitation: 633-647 nm; Emission: 723 nm; Laser: Red Laser

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. 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.
