G-Biosciences offers a wide range of non-radioactive bioassays for the detection of cell toxicity, cell death and cell proliferation that are ideal for high throughput screening.  Each CytoScan™ assay is designed for a microwell format and is suitable for studying chemical and cell-mediated cytotoxicity, viability, death or proliferation.
 

AlamarBlue Cell Viability Assay reagent quantitatively measures the proliferation of mammalian cell lines, bacteria and fungi. The dye incorporates an oxidation-reduction (REDOX) indicator that both fluoresces and change color in response to the chemical reduction of growth medium due to cell growth..

Calcein AM or Calcein acetoxymethyl ester is a hydrophobic compound which passes easily through cell membrane into live cells and is used for cell viability assays. The non-fluorescent calcein AM dye is hydrolyzed by cellular esterases to give calcein which is fluorescent and is retained in the cyto..
