Briefly, 48 hr post transfection cells have been lysed in TX100 lysis buffer containing 2 v/v from the non-ionic detergent, Triton X-100) plus a 16 concentration of SigmaFast Protease inhibitor applying electrophoresis buffer. For antibody-based detection, PVDF membranes have been blocked by incubation with 5 w/v nonfat dry milk reconstituted in PBS. For the detection of biotinylated proteins, membranes had been blocked by incubation in 3 w/v bovine serum albumin in PBS. Protein loading controls that happen to be shown are from identically loaded gels, which were transferred to PVDF membranes, stained with 0.01 w/v coomassie blue in.
