the results now obtained indicate that solubilization with a mild detergent ( 'chaps ' , 0.8 % ) of 125i-surface proteins of trypomastigotes , followed by detergent removal and interaction of the solubilized proteins with a monolayer of intact vero cells , brings about binding to the cells of a parasite surface protein , which exhibits a molecular weight of 83,000 and isoelectric point of 8.1-8.6 upon two-dimensional polyacrylamide gel electrophoresis .
