To provide a method for specifically determining CA isozyme activity.
The method for determining hydrolase activity of carbonic anhydrase I (CAI) in a sample, which is characterized in that the method employs, as a substrate or a combination of a substrate and an inhibitor, any of the following (A) to (E):
(A) Substrate: a substrate having higher reactivity with CAI than with CAII;
(B) Substrate: a substrate having higher reactivity with CAI than with CAII,
Inhibitor: an inhibitor inhibiting a hydrolase other than CA, and
an optional drug for enhancing inhibitory activity of the inhibitor;
(C) Substrate: a substrate having higher reactivity with CAI than with CAII, and
Inhibitor: a CA inhibitor inhibiting both CAI and CAII;
(D) Substrate: a substrate having reactivity with both CAI and CAII, and
Inhibitor: a CA inhibitor inhibiting CAI more potently than CAII; and
(E) Substrate: a substrate having higher reactivity with CAI than with CAII, and
Inhibitor: a CA inhibitor inhibiting CAI more potently than CAII.
提供一种特异性测定 CA 同工酶活性的方法。
确定样品中碳酸酐酶Ⅰ(CAI)水解酶活性的方法,其特征在于该方法采用以下(A)至(E)中的任一种作为底物或底物与抑制剂的组合:
(A) 底物:与 CAI 的反应活性高于与 CAII 的反应活性的底物;
(B) 底物:与 CAI 的反应活性高于与 CAII 的反应活性的底物、
抑制剂:抑制 CA 之外的水解酶的抑制剂,以及
增强抑制剂抑制活性的可选药物;
(C) 底物:与 CAI 的反应活性高于与 CAII 的反应活性的底物,以及
抑制剂:同时抑制 CAI 和 CAII 的 CA 抑制剂;
(D) 底物:与 CAI 和 CAII 都有反应性的底物,以及
抑制剂:对 CAI 的抑制作用强于 CAII 的 CA 抑制剂;以及
(E) 底物:与 CAI 的反应活性高于与 CAII 的反应活性的底物,以及
抑制剂:对 CAI 的抑制作用强于 CAII 的 CA 抑制剂。
