analysis of human platelet membrane proteins by crossed immunoelectrophoresis ( cie ) in the presence of triton x-100 ( tx-100 ) has previously shown that glycoproteins ( gp ) iib and iiia are located in a single immunoprecipitate , band 16.2 to investigate whether iib and iiia are associated in a complex , we have analyzed tx-100-solubilized 125i-labeled membrane proteins by density gradient ultracentrifugation using 10 % -40 % sucrose gradients containing the nonionic detergent . studies were performed using soluble proteins derived from membranes isolated in the presence or absence of edta .
