Pnpp standard curve
WebPNPP has apparent Km values for protein phosphatases in the range of 0.5 -10 mM (2-5). One unit of the protein phosphatase activity is defined as the amount of enzyme that hydrolyzes 1 nanomole of PNPP in one minute at 30°C in a total reaction volume of 50 μl … WebI have established pNP standard curve by taking pNP dilutions 0 to 1 mM (1 µmol/mL) in 20mM tris (pH ~6, optimum pH of my enzyme too). I added 1M sodium carbonate …
