Five x 105 CH7C17 tumor cells (HA1.7 Vb3+ transfectant) were washed and incubated 45 minutes on ice with 80 ul of anti-TCR Vb3/Biotin at 5 ug/ml. Cells were washed twice and incubated with 2 degree reagent Streptavidin/R-PE, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 1.6 log10 fluorescent units when compared to a Mouse IgG2a/Biotin negative control at a similar concentration. Binding was blocked when cells were pre incubated 10 minutes with 20 ul of 0.5 mg/ml anti-TCR Vb3 antibody.

Biotin

Antibody from (low FBS containing) tissue culture supernatant was Protein A purified to >95% mouse immunoglobulin by SDS-PAGE (<1% bovine immunoglobulin), and reacted with NHS-Biotin. Unconjugated Biotin was removed from conjugate using a desalting column.

50 mM Sodium Phosphate pH 7.5, 100 mM Potassium Chloride, 150mM NaCl, 5% Glycerol, 0.2% BSA, 0.04% NaN3 (as a preservative).
