Detection of tetrodotoxin (TTX) in whole-organ homogenates.
| Host Organism | Tissue tested | TTX concentration (mg/kg) |
|---|---|---|
| Hapalochlaena sp. | Posterior salivary gland | BDL a |
| Beak | BDL | |
| Pleurobranchaea maculata | Eggs | 5.19 |
| Digestive tract | 4.23 | |
| Reproductive tract | 3.84 | |
| Gonads | 3.54 |
a BDL indicates that the concentration of TTX was below the detectable limit of the instrumentation. The detection limit of TTX using the LC-MS method was 0.1 ng/mL (equivalent to 3 × 10−4 mg/kg of TTX in tissue).
