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 establish a clear structural relationship between the two polypeptides and are consistent with the hypothesis that the 22,000 dalton species derived proteolytically from the 26,000 dalton species.
人晶状体的细胞膜含有两种主要的多肽，分子量分别接近26,000和22,000。这两种物质已被高度纯化，并通过抗牛晶状体26,000道尔顿膜多肽的抗血清进行纯化。文中给出的免疫化学数据表明这两种多肽之间存在明确的结构关系，并且与22,000道尔顿的物质是由26,000道尔顿的物质经蛋白水解产生的这一假设相一致。
