The activated first component of complement (CI) possesses an esterase activity in vitro which will hydrolyse an ester of tyrosine to release H+. The activity of the serum inhibitor of C1 esterase may be measured by monitoring its ability to prevent H+ release under standard conditions. This paper describes a method of measuring such activity, monitoring H+ release by the use of either an acid base indicator of pH meter.
活化的补体第一成分(C1)在体外具有酯酶活性,它能水解酪氨酸酯以释放H⁺。C1酯酶血清抑制剂的活性可通过监测其在标准条件下阻止H⁺释放的能力来测定。本文描述了一种测量这种活性的方法,即使用酸碱指示剂或pH计监测H⁺的释放。
