【摘要】 利用超滤法从羊和猪的胎盘中提取胎盘肽,用改良的加脲Tricine-SDS-PAGE电泳法对其进行初步定性鉴定。成功分离显示出了羊的胎盘肽,其分子质量小于5 ku,与人胎盘肽的分子质量范围完全符合。猪的6 ku的蛋白带很明显,但低于5 ku的蛋白带不是很明显。更多还原

【Abstract】 The distilled caprine and swine placental peptide was prepared by ultrafilter and identified by improved Tricine-SDS-PAGE eletrophoresis with urea in the experiment.Caprine placental peptide was prepared and separated,which had no more than 5 ku of molecular weight,according with the molecular weight range of human placental peptide completely.As to swine placental peptide,the electrophoretic lane of 6 ku molecular weight was obvious,but less than 5 ku was obscure.更多还原
