Fig. 3From: Acute Intermittent Porphyria: Expression of Mutant and Wild-Type Porphobilinogen Deaminase in COS-1 CellsPulse-chase expression analysis of the wild-type and mutant PBGD polypeptides in COS-1 cells. During 1-hr pulse, all synthesized polypeptides were labeled with 35S-cysteine and 35S-methionine, and thereafter synthesized proteins were chased for 1, 4, and 23 hr, respectively. The wild-type and mutant polypeptides were immunoprecipitated and visualized by autoradiography after running the samples on an SDS-PAGE.Back to article page
