TCR V beta 5 Antibody (MEM-262) Summary

Human thymoma cell line HPB-ALL.
The antibody MEM-262 recognizes beta chains of the TCR expressed by HPB-ALL cell line [carrying V(beta5.3)] and a small subset of peripheral blood T cells. This subset is larger than that recognized by other V(beta5.3)-specific antibodies.
Protein A purified

Alternate Names for TCR V beta 5 Antibody (MEM-262)

  • T cell receptor beta locus
  • T-cell antigen receptor, beta polypeptide, T-cell receptor, beta cluster
  • T-cell receptor, beta cluster
  • TCRB
  • TRB


T cell receptors recognize foreign antigens which have been processed as small peptides and bound to major histocompatibility complex (MHC) molecules at the surface of antigen presenting cells (APC). Each T cell receptor is a dimer consisting of one alpha and one beta chain or one delta and one gamma chain. The beta locus includes V (variable), J (joining), diversity (D), and C (constant) segments. The Vbeta5 TCR is a variant of the TCR beta chain. It belongs to Ig superfamily and is expressed by a subset of peripheral blood T cells and some T cell clones. TCR Vbeta5 has been reported to recognize some staphylococcus bacterial superantigens.
