Description: This RR4-7 monoclonal antibody reacts with mouse V beta 6 TCR. Composed of an a and b chain, TCR specificity is typically determined by Va, Ja, Vb, Db, and Jb gene rearrangement. The RR4-7 antibody recognizes the V beta 6 chain on T cells from mouse strains with the a (e.g., C57BR and SJL) and b haplotypes (e.g., BALB/c, C3H, and DBA/1). Reports indicate that strains expressing the Mls-1a antigen, particularly in the presence of MHC Class II I-E, possess fewer V beta 6 TCR+ T cells.
The RR4-7 antibody has been reported to have functional activity in vitro and in vivo.
