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......閱讀全文

Promega在ASMS－2009上推出鑒定蛋白質的新途徑
Promega利用ProteaseMAX表面活性劑推出了一項創新簡化的膠內酶切技術。該項技術給分析人員提供了以下幾點好處： 節省時間：整個膠內酶切過程只需一個小時的時間 省去了萃取步驟：蛋白質分解和肽段回收一步完成。 更多的數據：該分解技術保持了原有肽段的信息。

蛋白酶解的首選變性劑——RapiGest－SF（二）
RapiGest SF雖然是一種表面活性劑，但其全面適應液質分析的要求。在使用RapiGest SF作為變性劑完成蛋白酶切后，如果只進行色譜分析，則可無需對RapiGest SF進行處理。如進行液質聯用分析，則通過簡單的加酸步驟就可將RapiGest SF去除。而酸性溶液環境又恰恰是液質
