BD, 553364, Biotin Rat Anti-Mouse Vβ4 T-Cell Receptor KT4

The KT4 antibody specifically recognizes the Vβ4 T-cell Receptor (TCR) of mice having the a (e.g., C57BR, C57L, SJL, SWR), b (e.g., A, AKR, BALB/c, CBA, C3H/He, C57BL, C58, DBA/1, DBA/2), and c (e.g., RIII) haplotypes of the Tcrb gene complex. Vβ4 TCR-bearing cells are among the CD4+ autoreactive T cells which induce autoimmune thyroiditis after elimination of regulatory (CD5-bright) T-cell subsets. Plate-bound KT4 antibody activates Vβ4 TCR-bearing T cells.
For flow cytometry of cell suspensions from peripheral lymphoid tissues, it is recommended that multicolor staining be performed to distinguish T lymphocytes from non-T cells.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with biotin under optimum conditions, and unreacted biotin was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.

3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
