CytoScan™ SRB Cytotoxicity Assay, G-Biosciences

G-Biosciences' CytoScan™ SRB Cytotoxicity Assay is a simple, accurate and reproducible assay based upon the quantitative staining of cellular proteins by sulforhodamine B (SRB).

G-Biosciences' CytoScan™ SRB Cytotoxicity Assay has been used for high-throughput drug screening at the National Cancer Institute. Sulforhodamine B is an anionic aminoxanthene dye that forms an electrostatic complex with the basic amino acid residues of proteins under moderately acid conditions, which provides a sensitive linear response. The color development is rapid and stable and is readily measured at absorbances between 560 and 580nm.

G-Biosciences' CytoScan™ SRB Cytotoxicity Assay is supplied in a kit that contains components sufficient for performing up to 1000 assays.
