Abstract

A sensitive and convenient "visible SYPRO" staining protocol was developed for visualizing proteins after SDS-PAGE. Gels were sensitized with SYPRO Ruby and then stained with the Coomassie Brilliant Blue G-250 protocol (Blue Silver). This combined protocol had similar or better linearity than staining with only SYPRO Ruby or Blue Silver, respectively. In addition, this method was more sensitive than that of Blue Silver, simpler than that of SYPRO Ruby, and compatible with subsequent mass spectrometry analysis.
