Pulse-chase analysis of [674C] and [674R]GPIIb-IIIa synthesis.
CHO cells, transiently transfected with cDNAs encoding GPIIIa and either normal [674C] or mutant [674R]GPIIb, were pulse-labeled with [35S]methionine for 30 minutes and then chased with medium containing unlabeled methionine. At the indicated times, the cells were lysed and immunoprecipitated with anti-GPIIb. The precipitates were analyzed by electrophoresis as described in “Materials and methods.”
