摘要

Method for the quantitative determination of serine proteases which includes contacting the substance for which the determination is desired with a diagnostically active chromogenic substrate with good stability and high specificity to serine proteases having the formula: H-D-A1-A2-A3-NH-R or salts thereof, wherein A1 is Gly, Ala, Val, Leu, Ile, Pip, Pro, or Aze; A2 is Gly, Ala, Val, Leu, Ile, Pip, Pro, Aze, or Phe; A3 is Arg, Lys, or Orn, and R is a chromophoric group.
