Pnpp assay
WebThe pNPP assay had a number of limitations, the first of which is the incubation temperature of the samples, 37°C. This temperature was shown during optimisation studies not to be the optimum for the lipase from Streptomyces clavuligerus and therefore, would demonstrate a lower lipase activity during the assay. WebJan 1, 2005 · For these phosphatases, pNPP can be used in an end-point assay where the reaction is stopped by raising the pH to measure the amount of product formed. The small size of pNPP limits the number of residues it interacts with, which is advantageous in establishing the extent to which a mutation affects the conformation of the active site of …
