1.14.18.1 | chymotrypsin | chymotrypsin is more effective in converting hemocyanin to hemocyanin-phenoloxidase than is trypsin | Penaeus vannamei | |
1.14.18.1 | SDS | hemocyanin-phenoloxidase activity increases with increasing concentrations of SDS, up to 2.22 mM | Penaeus vannamei | |
1.14.18.1 | Trypsin | trypsin has only a weak effect on hemocyanin conversion to hemocyanin-phenoloxidase, compared to SDS | Penaeus vannamei |
