The cross-reactivity of the 6/50 monoclonal anti-okadaic acid antibody (mAb) to the recently discovered diarrhetic shellfish poisoning (DSP) metabolites dinophysistoxin-4 (DTX-4), dinophysistoxin-5 (DTX-5), and an okadaic acid (OA) diol ester was determined using a competitive indirect enzyme-linked immunosorbent assay (ELISA). The reactivity of the antibody to these molecules was compared to that with OA; the 6/50 mAb recognized all of these DSP compounds with equal sensitivity within the working range of the antibody (10-100 nM for OA). This confirms the ability of the antibody to detect all DSP compounds when used in analyses including ELISA and immunocytochemistry.
使用竞争性间接酶联免疫吸附测定（ELISA）法，测定了6/50抗冈田酸单克隆抗体（mAb）与最近发现的腹泻性贝类毒素（DSP）代谢产物鳍藻毒素-4（DTX-4）、鳍藻毒素-5（DTX-5）以及一种冈田酸（OA）二醇酯的交叉反应性。将该抗体对这些分子的反应性与对OA的反应性进行了比较；在抗体的工作范围内（OA为10 - 100 nM），6/50 mAb以相同的灵敏度识别所有这些DSP化合物。这证实了该抗体在用于包括ELISA和免疫细胞化学在内的分析时，能够检测所有DSP化合物。
