Product overview
WST-1 Cell Proliferation Assay Kit (ab65473) provides by far the easiest and most sensitive means for performing a quantitative cell proliferation assay, cell viability assay, or cytotoxicity assay in mammalian cells. It is also available in a ready-to-use reagent format: ab155902.
The WST-1 assay protocol is based on the cleavage of the tetrazolium salt to formazan by cellular mitochondrial dehydrogenase. The amount of the dye generated by activity of dehydrogenase is directly proportional to the number of living cells. The formazan dye produced by viable cells can be quantified by microplate reader by measuring the absorbance of the dye solution at 440 nm.
The WST-1 assay is just add-and-read, requiring no washing, no harvesting, and no solubilization steps. It is faster, stable, and more sensitive than MTT, XTT, MTS based assays. The assay correlates well with the [3H]-thymidine incorporation assay.
The WST-1 assay protocol is very simple:
- add the WST-1 assay reagent to the cell culture media and incubate for between 0.5 and 4 hrs
- shake the plate to mix the contents
- analyze the amount of formazan dye produced by measuring the absorbance at 440 nm -
Notes
This product is manufactured by BioVision, an Abcam company and was previously called K301 Quick Cell Proliferation Colorimetric Assay Kit. K301-500 is the same size as the 500 test size of ab65473.
