Use of a channel biosensor for the assay of paralytic shellfish toxins
Toxicon, 1998Gonyautoxin (GTX), saxitoxin (STX) and tetrodotoxin (TTX), also known as paralytic shellfish poisons (PSP), block Na+ channels, including those in the frog bladder membrane. A tissue biosensor has been developed, consisting of a Na+ electrode covered with a frog bladder membrane integrated within a flow cell. The direction of Na+ transfer, investigated

Transformation of Paralytic Shellfish Toxins as Demonstrated in Scallop Homogenates
Science, 1981Toxins in shellfish, which are responsible for paralytic poisonings, undergo reductive transformation when incubated with the homogenate of various portions of the scallop, Placopecten magellanicus . The transformation includes the reductive elimination of O -sulfate groups, a change that is ...

Paralytic shellfish toxins in bivalves which are not associated with dinoflagellates
Toxicon, 1989Paralytic shellfish toxins (PSP toxins) were detected in the freshwater bivalve Corbicula sandai collected from Lake Biwa, Shiga Prefecture, Japan, and marine mussel Septifer virgatus from Mutsu Bay where known causative dinoflagellates and their cysts have never been observed. The toxin profile of C. sandai and S.

Solid-Phase Radioreceptor Assay for Paralytic Shellfish Toxins
Analytical Biochemistry, 1993Sodium channels obtained from rat brain membrane preparations were coated onto microtiter plates and used to develop a direct solid-phase binding assay. The tritiated sodium channel blocker saxitoxin ([3H]-saxitoxin; STX) was used to detect toxins in paralytic shellfish poisoning (PSP) by measuring the competitive displacement of other toxins.

Standardized extraction method for paralytic shellfish toxins in phytoplankton
Journal of Applied Phycology, 1995The optimal conditions were established for extraction of paralytic shellfish toxins from a Danish clone of Alexandrium tamarense using extraction with acetic acid and HCl in the concentration range 0.01–1.0 N. Physical destruction of the cells was investigated microscopically to select the most efficient extraction procedure.

Determination of paralytic shellfish poisoning (PSP) toxins in UK shellfish
Harmful Algae, 2007Abstract A study was conducted to aid the interpretation of data generated by parallel testing of the qualitative Jellett Rapid Test (JRT) and the mouse bioassay (MBA) for detection of paralytic shellfish poisoning (PSP) toxins within the UK statutory shellfish biotoxin monitoring programme.

Investigation of Extraction Method for Paralytic Shellfish Poisoning Toxins in Shellfish
Chinese Journal of Analytical Chemistry, 2008Me optimal conditions were established for the extraction of paralytic shellfish poisoning toxins from gonad of Chlamys nobills using acetic acid and hydrochloric acid in the concentration range of 0.04-1.0 mol/L. A 10-g portion of gonad of Chlamys nobilis was extracted by boiling for 5 min with 1.0 mL acetic acid and hydrochloric acid in a 50-mL ...
