Effect of organic solvents on activity of PyCP.
| Solvents | Residual activity (25%) |
| Chloroform | 40.01 ± 2.5 |
| Butanol | 22.57 ± 11.1 |
| Methanol | 82.39 ± 1.1 |
| Ethanol | 72.20 ± 2.3 |
| Formaldehyde | 8.04 ± 6.8 |
| Acetone | 89.39 ± 0.3 |
| Formamide | 100.85 ± 0.5 |
| Isopropanol | 51.97 ± 2.8 |
PyCP was incubated with 25% of the solvent for 60 min at 40°C and the residual activity was measured under standard assay conditions.
