Coimmunoprecipitation of BiP with [674R]GPIIb-IIIa complex.
CHO cells, transiently cotransfected with cDNAs encoding GPIIIa and either normal [674C]GPIIb or mutant forms of GPIIb, were immunoprecipitated with the indicated antibodies. The precipitates were analyzed by electrophoresis, transferred to nitrocellulose membrane, and blotted with polyclonal anti-BiP antibody, as described in “Materials and methods.”
