Neutral Red Assay Kit - Cell Viability / Cytotoxicity

Product details

Neutral Red Assay Kit - Cell Viability/Cytotoxicity (ab234039) is simple, accurate and reproducible. This kit offers an excellent and efficient method for in vitro cytotoxicity studies as well as high-throughput drug screening that can detect between 5,000-50,000 cells per well. It includes Doxorubicin as a positive control.

Neutral red cell cytotoxicity assay is one of the common methods used to detect cell viability or drug cytotoxicity. The principle of this assay is based on the detection of viable cells via the uptake of the dye neutral red. Neutral red is a eurhodin dye that stains lysosomes in viable cells. Viable cells can take up neutral red via active transport and incorporate the dye into their lysosomes but non-viable cells cannot not take up this chromophore. Consequently, after washing, viable cells can release the incorporated dye in under acidifiedextracted conditions. The amount of released dye can be used to determine the total number of viable cells or drug cytotoxicity. The neutral red uptake assay provides a quantitative measurement of the number of viable cells and can be measured at OD 540 nm.

This product is manufactured by BioVision, an Abcam company and was previously called K447 Neutral Red Cell Cytotoxicity Assay Kit. K447-1000 is the same size as the 1000 test size of ab234039.
