title: Antibodies to brevetoxin B: serologic differentiation of brevetoxin B and brevetoxin A.
abstract: A brevetoxin B immunogen was prepared by reacting brevetoxin B with the amino groups of bovine albumin followed by treatment with sodium borohydride. Immunized rabbits produced antibodies that bound [3H]brevetoxin B-alcohol. This binding increased with repeated immunization (KD for one rabbit after three courses of immunization was about 10 pM). Brevetoxin B inhibited greater than 500 times more effectively than brevetoxin A. When tested in a competitive binding assay with [3H]brevetoxin B-alcohol-brevetoxin B antibody, the alcohol was six times more effective as an inhibitor than brevetoxin B. Despite some similarities in structure with brevetoxin A, the antibodies to brevetoxin B did not recognize the backbone of brevetoxin A.
