摘要: A simple procedure for spectrophotometric determination of proteolytic activity in coloured solutions is described. Gelatin cross-linked with glutaric dialdehyde or formaldehyde the presence black drawing ink used as an insoluble chromolytic substrate. The absorbances reaction mixture filtrates are read near infra-red region (at 800-900 nm) where majority substances does not absorb; on contrary released from substrate during proteolysis absorbs strongly even at these wavelengths.
