Abstract

Human erythrocyte glycophorin was purified rapidly by (a) chromatography of a Triton X-100 extract of erythrocyte 'ghosts' on N-(3-carboxypropionyl)aminodecyl-Sepharose in buffers containing Triton X-100 or sodium dodecyl sulphate, or (b) chromatography of whole 'ghosts', solubilized in sodium dodecyl sulphate, on dodecyl-Sepharose, in buffers containing sodium dodecyl sulphate. The products contained 85-95% glycophorin (electrophoretic band PAS-1) and the major contaminants were glycoproteins PAS-2 (possibly a subunit of glycophorin) and PAS-3.

摘要

人红细胞血型糖蛋白可通过以下方法快速纯化

(a) 在含有 Triton X-100 或十二烷基硫酸钠的缓冲液中,将红细胞“血影”的 Triton X-100 提取物在 N-(3-羧基丙酰基)氨基十二烷基-琼脂糖上进行层析;或(b) 将溶解在十二烷基硫酸钠中的完整“血影”在含有十二烷基硫酸钠的缓冲液中的十二烷基-琼脂糖上进行层析。产物中含有 85 - 95%的血型糖蛋白(电泳带 PAS-1),主要污染物是糖蛋白 PAS-2(可能是血型糖蛋白的一个亚基)和 PAS-3。
