The antibody 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.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Flow Cyt: Use at an assay dependent dilution.
IP: Use at an assay dependent dilution.
WB: Use at an assay dependent dilution. Uniquely recognizes denatured TCR beta chains under the conditions of Western blotting.
Not tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
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 Vß5 TCR is a variant of the TCR ß chain. It belongs to Ig superfamily and is expressed by a subset of peripheral blood T cells and some T cell clones. TCR Vß5 has been reported to recognize some staphylococcus bacterial superantigens.
