Protocols

Beta-amylase is found in bacteria, fungi, and plants. To measure β-amylase activity, this assay uses a colorimetric spectrophotometric stop reaction at 540 nm.

Follow our procedure for the determination of alpha-Amylase activity. This enzymatic assay of a-Amylase guides you through the entire process and necessary calculations.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
