Electrophoretic analysis of paralytic shellfish toxins
Journal of Environmental Science and Health . Part A: Environmental Science and Engineering, 1977Abstract Seven paralytic shellfish poisons (PSP) from the dinoflagellate Gonyaulax tamarensis and PSP infested shellfish have been separated by cellulose acetate membrane strip electrophoresis. The acid hydrolysis products of two of these, saxitoxin and neosaxitoxin, are analyzed by electrophoresis.

Synthesis of Paralytic Shellfish Toxins: Saxitoxins
2020Saxitoxin (STX), which is isolated as a paralytic shellfish toxin, is an inhibitor of voltage-gated sodium channels (NaVCh) such as tetrodotoxin. STX has two guanidine functional groups in its tricyclic core structure, and every carbon except at C11 connects heteroatoms.

Toxicon, 1987
Paralytic shellfish toxins in both cultured cells and natural phytoplankton blooms of the dinoflagellate Gymnodinium catenatum from inshore Tasmanian waters (Australia) were analyzed by high performance liquid chromatography, thin layer chromatography and electrophoresis techniques. The dinoflagellate toxins were dominated by low potency sulfocarbamoyl

Analytical and Bioanalytical Chemistry, 2021
Accurate analysis of paralytic shellfish toxins (PSTs) in shellfish is important to protect seafood safety and human health. In this study, the performance of different extraction protocols for PSTs from scallop tissues is compared and discussed, including regular extraction solvents hydrochloric acid (HCl) and acetic acid (AcOH) followed by heating ...

A toxin profile for shellfish involved in an outbreak of paralytic shellfish poisoning in India
Toxicon, 1990Toxin profiles of clams and oysters involved in the outbreak of paralytic shellfish poisoning in India in 1983 were studied by a liquid chromatographic technique. Gonyautoxins 1, 2, 3, 4 and 8, and 11-epigonyautoxin 8 appeared to be the major toxins along with small amounts of saxitoxin, neosaxitoxin, decarbamoylsaxitoxin, decarbamoylgonyautoxins 2 and

Exposure assessment to paralytic shellfish toxins through the shellfish consumption in Korea
Food Research International, 2018Paralytic shellfish poisoning is caused by saxitoxin and its analogues. The paralytic shellfish toxins (PSTs) are produced by marine dinoflagellates and can be accumulated in filter feeding shellfish, such as mussel, clam, oyster and ark shell. The worldwide regulatory limits for PSTs in shellfish are set at 80 μg STX eq./100 g meat and this is widely ...

Development of reference materials for paralytic shellfish poisoning toxins.
Journal of AOAC International, 2001A project was undertaken to develop mussel reference materials that were certified for their mass fractions of saxitoxin and decarbamoyl-saxitoxin. Fifteen laboratories from various European countries participated. Three of these had major responsibility for substantial parts of the work and overall coordination of the project.

Potentiometric chemical sensors for the detection of paralytic shellfish toxins
Talanta, 2018Potentiometric chemical sensors for the detection of paralytic shellfish toxins have been developed. Four toxins typically encountered in Portuguese waters, namely saxitoxin, decarbamoyl saxitoxin, gonyautoxin GTX5 and C1&C2, were selected for the study.

Instrumental Methods for Paralytic Shellfish Toxins
2015Paralytic shellfish toxins (PSTs) are naturally occurring marine compounds which in some instances result in significant consumer sickness following consumption of contaminated shellfish products. The toxins are found in shellfish grown in marine waters throughout the world, and many instances of human intoxication are reported annually.
