Summary: Isopropanol Dehydrogenase Activity Colorimetric Assay Kit provides a convenient tool for sensitive detection of the ADH1- NADP in a variety of samples. In this assay, Isopropanol gets converted to Acetone and NADPH in the presence of NADP+ . This results in the development of colour in the presence of the developer. This colour is proportional to the ADH1-NADP levels in the sample and can be measured at λ = 450 nm. This assay detects ADH1-NADP activity as low as 0.001 mU in samples.
