Abstract:
A polyclonal antiserum generated against crab saxitoxin-induced protein was tested against paralytic shellfish poison (PSP)-contaminated crabs and shellfish. Antibody-reactive proteins in PSP-contaminated bivalve mollusc extracts were localized using SDS-PAGE and immunoblotting. PSP-contaminated clams and oysters possessed a higher degree of immunoreactivity to the saxitoxin-induced protein found in PSP-resistant crabs than their respective non-contaminated controls.
