SRB Cytotoxicity Assay Kit



SRB Cytotoxicity Assay Kit is an excellent and efficient assay to evaluate cytotoxicity and cell viability. It is based in the staining of cellular proteins with the bright pink aminoxanthane dye, sulforhodamine B (SRB). SRB forms an electrostatic complex with basic amino acid residues in labeling acidic conditions, but it can dissociate under solubilization basic conditions.

The binding of SRB is stochiometric. The incorporated dye solubilized is directly proportional to the cell number. The assay readout is colorimetric at 540 nm with a reference at 690 nm.

Research Use Only. Not for use in diagnostic procedures.
