Abstract

Heterogeneity of the active substance of Lipotropin-Polfa preparation was investigated by the method of gel column chromatography. The isolated polypeptide hormone has been found to possess the average molecular weight nine times smaller than that reported in the literature. This polypeptide was separated into six fractions by chromatography on Sephadex G-10. These fractions were found to differ in respect of the qualitative and quantitative amino acid composition. With the purpose of comparison, an analogous study of Lipormone-Labor. Choay (France) was performed. Similarity of this preparation to fraction I of Lipotropin-Polfa has been shown.

摘要

采用凝胶柱色谱法研究了多法脂解素制剂活性物质的异质性。已发现分离出的多肽激素的平均分子量比文献报道的小九倍。该多肽通过在葡聚糖G - 10上的色谱法分离成六个组分。发现这些组分在定性和定量氨基酸组成方面存在差异。为了进行比较，对法国乔雅实验室的脂激素进行了类似研究。已表明该制剂与多法脂解素的组分I相似。
