  • .beta.-Amylase determination
    Patent number: 4550077
    Abstract: A reagent suitable for .alpha.-amylase determinations. The reagent contains a modified, blocked amylaceous polysaccharide substrate, e.g., starch glyolate, an exating by amylose, a buffer and an enzymatic glucose measuring system. The glycolate substrate is selected such that the ratio of methylated glucose to glucose is between 1:4 to 1:16. The system permits an impid assay in a single vid within 7 minutes and can be automated.
