Plasma basic carboxypeptidase activity
| CPB2 activity (mOD/min) | CPN activity (mOD/min) | |
|---|---|---|
| WT (n = 3) | 0.15 ± 0.06 | 1.60 ± 0.16 |
| Cpb2−/− (n = 3) | 0.02 ± 0.03 | 1.80 ± 0.22 |
| Cpn−/− (n = 3) | 0.17 ± 0.05 | 0.01 ± 0.01 |
| Cpb2−/− / Cpn−/− (n = 5) | 0.04 ± 0.05 | 0.03 ± 0.04 |
Citrated plasma, collected from the four genotypes, was assayed for carboxypeptidase N (CPN) and carboxypeptidase B2 (CPB2) activity. WT, wild type.
