Abstract

蛋白质凝胶电泳方法分离,可以检测到几种染色方法。本单位介绍四种常用方法检测蛋白质的协议。考马斯亮蓝染色是一个简单而快速的方法。银染,而更多的时间消耗,是相当多的敏感,因此可以用来检测蛋白质的数额较小。荧光染色法是一种流行的替代传统的染色程序,主要是因为它比考马斯染色更敏感,往往是如银染敏感。这里还展示了与SYPRO Orange和SYPRO Ruby的蛋白质染色。

  4. A good and cheap alternative to SYPRO Rubi is RuBPS staining. Here are some protocols. More information can be found on www.ruthenium.ag.vu   RuBPS staining protocol I (quality) 1. Fix the gel in 30% EtOH, 10% acetic acid overnight ². Rinse the gel in ²0% EtOH for 30 min and repeat 3 times 3. Incubate the gel in 1 mM RuBPS solution for 6 h 4. Equilibrate the gel in water for 10 min and repeat once 5. Destain the gel with 40% EtOH/10% acetic acid for 15 h 6. Equilibrate the gel in water for 10 min repeat once and scan   all% are in V/V   Procedure as published in Proteomics ²004, 4, 599–608.     RuBPS staining protocol II (fast)   1. Incubate the gel in 50 ml of 40% Ethanol/10% acetic acid containing    1 mM RuBPS for 1 h. ². Destain the gel for ²0 min in 40% Ethanol/10% acetic acid 3. Wash the gel for 10 min in water and scan   all% are in V/V   Procedure as published in PLoSONE. ²007 Feb ²8;²(²)e²63.       RuBPS staining protocol III (co-electrophoretical)   1. Add 1 ml of ²0 mM stock solution to one pocket of your SDS gel. Run     the gel according to your standard procedure. ². Incubate the gel in 50 ml of 40% Ethanol/10% acetic acid for ²0 min 3. Incubate the gel in 50 ml water for 10 min and scan       RuBPS staining protocol IV (loading buffer)   1. Add 1 ml of ²0 mM stock solution to your loading buffer (omit all other     dyes like bromophenol blue). Run the gel according to your standard     procedure. ². Incubate the gel in 50 ml of 40% Ethanol/10% acetic acid for ²0 min 3. Incubate the gel in 50 ml water for 10 min and scan
