abstract：:Cell membranes from the human lens contain two major polypeptides with molecular weights near 26,000 and 22,000. These two species have been isolated in a highly purified state and purified by means of an antiserum against the 26,000 dalton membrane polypeptide from bovine lens. Immunochemical data are presented that ...
