WebbThe Histone Demethylase Activity kit is to quantitatively measure the enzymatic activity of formaldehyde-producing enzymes such as histone demethylases. The kit is unique in that the product of these enzymatic demethylation reactions, formaldehyde, is quantitated directly by a fluorescent product. No separation or washing is required.
