Crystal violet binding assay
WebThe application of a simple, rapid, and inexpensive colorimetric growth assay was tested for human epidermal cells subcultured in uncoated plastic dishes. Cell layers were incubated with a crystal violet (CV) solution (0.2% with ethanol 2% in 0.5 M Tris-Cl buffer, pH 7.8) for 10 min at room temperature. WebThe Crystal Violet assay assumes that all cells that are attached to the plate are "alive" and that all cells that detach are "dead". Crystal violet is a triarylmethane dye that binds to ribose type molecules such as DNA in …
