Activities of physiologically active substances such as endopeptidases, proteases, transferases, phosphatases, protein kinase and the like enzymes can be measured specifically with high sensitivity by using as a substrate a peptide derivative having 2 to 15 amino acid units and a group which can emit fluoresence and/or absorb ultraviolet light as at least one terminal group.
生理活性物质的活性,如内肽酶、
蛋白酶、转移酶、
磷酸酶、蛋白激酶等酶可以通过使用具有2至15个
氨基酸单元和至少一个可以发射荧光和/或吸收紫外线的基团的肽衍
生物作为底物来高度特异性地测量。
