Abstract
A surface plasmon resonance (SPR) optical biosensor method was developed for the detection of paralytic shellfish poisoning (PSP) toxins in shellfish. This application was transferred in the form of a prototype kit to seven laboratories using Biacore QSPR optical biosensor instrumentation for interlaboratory evaluation. Each laboratory received 20 shellfish samples across a range of species including blind duplicates for analysis. The samples consisted of 4 noncontaminated samples spiked in duplicate with a low level of PSP toxins (240 mu g STXcliHCl equivalents/kg), a high level of saxitoxin (825 mu g STXdiHCl/kg), 2 noncontarninated, and 14 naturally contaminated samples. All 7 participating laboratories completed the study, and HorRat values obtained were
