Abstract
A major sialoglycoprotein from rat epididymal fluid was radiolabeled by NaIO4/[3H]KBH4 method and purified by chromatography using DEAE-Sepharose and chromatofocusing columns. Its Mr was 21,000 and its pI value was 4.9. Since it possessed a high sialic acid content and an alpha-lactalbumin-like activity, it was proposed to be a sialylated form of epididymal alpha-lactalbumin-like protein.
摘要
采用高碘酸钠/[3H]硼氢化钾法对大鼠附睾液中的一种主要唾液糖蛋白进行放射性标记，并通过使用DEAE-琼脂糖和色谱聚焦柱的色谱法进行纯化。其分子量为21,000，等电点值为4.9。由于它具有高唾液酸含量和α-乳白蛋白样活性，因此被认为是附睾α-乳白蛋白样蛋白的唾液酸化形式。
