肝素由葡萄糖醛酸和硫酸氨基葡萄糖分子相间组成,是一种酸性粘多糖类物质。对肝素的鉴别,多采用琼脂糖凝胶电泳法,该法系利用肝素在醋酸-锂盐缓冲液(ph3.0)中带强负电荷,在电场中向正极移动的性质进行鉴别。但该法所用试剂如琼脂糖较昂贵,故笔者研究了以琼脂平板电泳鉴别肝素的方法,该法所用试剂价廉易得,且分离效果也很好,现介绍如下。 Heparin is composed of glucuronic acid and glucosamine sulfate molecules and is an acidic mucopolysaccharide substance. The identification of heparin, and more use of agarose gel electrophoresis, the law of the use of heparin in acetic acid - lithium salt buffer (ph3.0) with a strong negative charge in the electric field to move to the positive nature of the identification. However, the reagents used in this method, such as agarose, are more expensive. Therefore, the author studied the method of identifying heparin by agar plate electrophoresis. The reagent used in this method is cheap and easy to obtain and the separation effect is also very good.
