I did the amylase inhibition assay and confirm the color of final mixture was good. Enzymatic method for determining amylase activity amylase. Ghi on pancreatic amylase was observed over a wide range of. After measuring absorbance, inhibition % was calculated. The absorbance of the mixture measured at 517 nm after 2 min. Amylase activity is determined using a coupled enzymatic assay, which results in a colorimetric 405 nm product, proportional to the amount of substrate, ethylidenepnpg7. This assay protocol is suitable for the colorimetric detection of amylase activity in cell and tissue culture supernatants, urine, plasma, serum, and other biological samples using the amylase activity assay kit mak009.

Without seeing your data, it is somewhat for me to say but you should read this book, which can be downloaded freely from the internet. L of the test extract was allowed to react with 200.
