Molecular Probes' proprietary Coomassie Fluor Orange protein gel stain provides fast, simple, sensitive staining of proteins separated by SDS-PAGE. After electrophoresis, the gel is stained, rinsed and photographed. Staining is complete in less than an hour – no separate fixation or destaining steps are required, and there is no risk of overstaining the gel. Stained proteins can be visualized using a standard 300 nm UV transilluminator or a laser-based scanner. Coomassie Fluor Orange protein gel stain is also available in a 5 liter size (Cat. no. C-33251).
