Product overview
Crystal Violet Assay Kit ab232855 is used for cytoxicity and cell viability studies with adherent cell cultures.
The Crystal Violet assay is based on staining cells that are attached to cell culture plates. It relies on the detachment of adherent cells from cell culture plates during cell death. During the assay, dead detached cells are washed away. The remaining attached live cells are stained with Crystal violet. After a wash step, the Crystal violet dye is solubilized and measured by absorbance at 595 nm.
The amount of Crystal Violet staining in the assay is directly proportional to the cell biomass that is attached to the plate. The cell biomass can be used to infer levels of cell viability / cytotoxicity. The 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 nuclei.
