Biolegend, 156302, Purified anti-mouse TCR vβ8.3 Antibody, 500μg

The TCR Vβ8 family consists of three members, namely Vβ8.1, 8.2 and 8.3. 1B3.3 reacts with Vβ8.3 only, but not Vβ8.1 or Vβ8.2. Most mouse strains have about 20% Vβ8+ T cells in the periphery. However, C57BR, C57L, SJL, SWR (Tcra haplotype) and RIII strains (Tcrc haplotype) do not express Vβ8 due to a gene deletion at the Vβ8 loci.  Exogenous superantigen, such as staphylococcal enterotoxin B, stimulates lymphocytes bearing Vβ8 and selectively eliminate those T cells in vivo .
