2. Protein Separation

Sample Preparation: 1 million cells from cell line K526 were lysed in an immuno-precipitation buffer containing 20 mM Tris-HCL (pH 7.6), 150 mM NaCl, 1mN EDTA, 0.1% NP-40, 100ug/ml PMSF, and 1mM sodium vanadate. Cell lysates were vortexed on ice for 30 minutes and spun to clear. The Supernatant was then incubated with protein A, and then with ABL1 specific antibody that has already been bound to protein A. Samples were incubated overnight, washed and then the beads were boiled in gel loading buffer and run for 1 hour on an SDS page gel (12% Bis-Tris). Resulting gel bands were then excised, reduced, alkylated and digested overnight with trypsin.
