Description: This MR12-3 monoclonal antibody reacts with the T cell receptor (TCR) V beta 13 chain. Composed of an alpha and beta chain, TCR specificity is typically determined by Va, Ja, Vb, Db, and Jb gene rearrangement. The MR12-3 antibody recognizes the V beta 13 chains on T cells from mouse strains with the b haplotype of the Tcrb gene, including C57BL/6, B10, and C3H. V beta 13+ T cells are deleted in mouse strains with the a (e.g., SJL) and c (e.g., RIIIS/J) haplotypes.
The MR12-3 monoclonal antibody has been reported to have blocking activity.
