Reaction assay

WebEnzymatic assays often use spectrophotometric detection of a signal at a particular wavelength. For example, an enzymatic assay of ethyl alcohol (alcohol) utilizes alcohol dehydrogenase enzyme to oxidize ethyl alcohol into acetaldehyde. In this process co-factor NAD (nicotinamide adenine dinucleotide) is converted into NADH. WebReaction definition, a reverse movement or tendency; an action in a reverse direction or manner.
