| 摘 要： | 香葱叶片经生理盐水抽提、硫酸铵沉淀、Ｓｅｐｈａｄｅｘ Ｇ－７５和Ｂｏ－ＧｅｌＰ－３０柱层析分离得到香葱凝集素。该凝集经聚丙烯酰胺凝胶电泳、糖蛋白色均显示单一条带。ＳＤＳ－聚丙烯酰胺凝胶电泳测得两条带相对分子质量分别为２９０００和２３０００，表明该凝集素是由两个不同的亚基组成。

| Abstract: | The lectin from Allium ascalonicum L. was obtained by extraction with physiological saline, precipitation with ammonium sulfate, chromatography purification on Sephadex G-75 and Bio-Gel P-30. It turned out to be a single band in PAGE identification with HIO4-Schiff agent reaction, which identified it as a purified glycoprotein. Its molecular weight was approximately 51000 by Sephadex G-200 analysis. SDS-PAGE gave two The hemagglutination of the lectin on rabbit erythrocytes was inhibited by L-rhamnose and D-mannose among the sugar tested . |
