Bio-Rad Laboratories, Inc. announced the launch of the Criterion Stain Free imaging system, designed to enable stain-free detection and quantitation of proteins. The system consists of a new formulation of Bio-Rad’s Criterion precast gels, a Criterion Stain Free imager, and Image Lab software.
The Criterion Stain Free system enables scientists to bypass the staining and de-staining steps of SDS-PAGE and visualize protein samples in two and one half minutes after electrophoresis, according to Bio-Rad Laboratories. In addition, the system captures digital images of gels to make record keeping easy and gel drying obsolete.
Key benefits of the system are: gel images may be obtained in as little as two minutes after electrophoresis, one-touch instrument operation, equal or improved sensitivity compared to a Coomassie stain, compatible with western blotting and mass spectrometry, the need for gel drying step is eliminated, and no organic waste as the result of the process, according to the company.
