An improved immunoassay for detecting cannabinoids is described. This immunoassay is characterized by utilizing, as reagents, antibody, 125I-radiolabeled antigen, an unlabeled antigen and an anion exchange resin for separation of labeled and unlabeled antigen. The iodinated tetrahydrocannabinol moiety is stabilized by the addition of small quantities of antioxidants such as butylated hydroxytoluene.
描述了一种用于检测大麻素的改进型免疫测定法。 该免疫测定法的特点是利用抗体、125I-放射性标记抗原、未标记抗原和阴离子交换树脂作为试剂,用于分离标记抗原和未标记抗原。 通过添加少量抗氧化剂(如丁基羟基甲苯)来稳定碘化四氢大麻酚分子。
