A rapid procedure for determining salivary- and pancreatic-type amylase (EC 3.2.1.1) in serum by incorporating a wheat germ inhibitor (from Triticum aestivum) was developed for the Du Pont aca IV analyzer. Under optimal assay conditions, activities of salivary and pancreatic amylase were inhibited by 93% and 19%, respectively.來源：https://pubmed.ncbi.nlm.nih.gov/2426009/

Amylase分為S型(唾液型)及P型(胰臟型)，小麥胚芽抑制劑僅能結合S型。
