Ingeldigestionofproteinsforpeptidefingerprintmapping
Polyacrylamide gel electrophoresis is a widely used technique to separate proteins from biological samples. Moreover, the development of two-dimensional (2D) gel electrophoresis has provided a tool for differential protein display, which allows for the quantitative analysis of many (~500-1000) of proteins simultaneously. Complex biological questions can now be approached by analyzing differences in the 2D gel pattern......阅读全文

蛋白酶解的首选变性剂——RapiGest－SF（二）
RapiGest SF虽然是一种表面活性剂，但其全面适应液质分析的要求。在使用RapiGest SF作为变性剂完成蛋白酶切后，如果只进行色谱分析，则可无需对RapiGest SF进行处理。如进行液质联用分析，则通过简单的加酸步骤就可将RapiGest SF去除。而酸性溶液环境又恰恰是液质
