Abstract

Abstract A new soluble chromogenic substrate for α-amylase was prepared by coupling partially hydrolyzed starch with a dye, Ostazin brilliant red H-3B. The substrate is precipitable from buffered solutions with ethanol and is equally suitable for assay of α-amylase, detection of separated α-amylase isoenzymes in gels, and selection of microbial producers of the enzyme.
