SYPRO® Red Protein Gel Stain is a highly sensitive, fluorescent protein gel stain that detects as little as 4-8 ng protein per band. Staining is easy - simply soak gels in a solution of 1X SYPRO® Red in 7.5% acetic acid for 40 to 60 minutes. The stain is compatible with UV transilluminators, CCD cameras or laser scanners. SYPRO® Red Protein Gel Stain is supplied as 10 x 50 µl or 500 µl as a 5,000X concentrate, sufficient for staining approximately 50 minigels.
