摘要: 介绍一种检测SDS聚丙烯酰胺凝胶电泳中家蝇幼虫蛋白的新方法-海波银染法。该方法对传统银染方法中的试剂与步骤加以改进,省略了乙醇固定与洗涤步骤,只需20 min即可完成全部染色过程,且仅在国产分析纯试剂及普通操作条件下,灵敏度可达毫微克级水平。

Abstract: A new Na2S2O4 silver staining method is described for detecting the proteins of housefly separated by SDS-PAGE. In this staining method, besides the regents and steps are different from the classical silver staining method, fixation and ethanol washing are not necessary. Only twenty minutes were needed to complete the whole staining process. This method has a low demand for regents and manipulation, but can still reach the sensitivity level of nanogram.
