polyacrylamide gel electrophoresis of 125i-labeled membrane hspg immunoprecipitated with these mabs revealed that mabs 1c7 and 2e9 bind only membrane hspg which yield a 125-kda core protein after heparitinase digestion , whereas mab s1-bound hspg yield a 64-kda core protein , and mabs 6g12 and 10h4 retain membrane hspg with a 48-kda core protein .
