Incorporation of radioactivity from 32P-NAD into DNA adducts by extracts from shellfish
| Species | Activity |
|---|---|
| M. lamarckii (hard clam) | 6,900 |
| R. philippinarum (littleneck clam) | 2,300 |
| C. japonica (brackishwater clam) | 1,790 |
| My. galloprovincialis (blue mussel) | 450 |
| So. strictus (razor clam) | 190 |
| Sp. sachalinensis (surf clam) | 189 |
| B. middendorffi* (whelk) | 74 |
| Cr. gigas (Pacific oyster) | 25 |
| Atrina pectinata (pen shell) | 18 |
| B. inclytum* (whelk) | 3 |
| T. cornutus* (turban shell) | <1 |
| Ma. chinensis (hen clam) | <1 |
| Tr. keenae (softshell) | <1 |
| Sc. broughtonii (blood clam) | <1 |
Activity was calculated by densitometric analysis of DNA adducts and is expressed as PSL per microgram of protein. Activity of pierisin-1 was ≈10 PSL per picogram of protein.
*Gastropods (all others are bivalves).
