Abstract
The glycoproteins of human erythrocyte membranes were crosslinked with dimethyl adipimidate dihydrochloride. On sodium dodecyl sulfate-polyacrylamide gel electrophoregrams of the crosslinked solubilized membranes, at least three new glycoprotein complexes appeared in addition to the normal glycoprotein species. One of the new glycoprotein complexes was shown to contain two of the three species of membrane glycoproteins.
