Abstract

Four high affinity monoclonal antibodies, which recognize two plant growth regulators from the cytokinin group, namely trans-zeatin riboside and dihydrozeatin riboside and their derivatives are reported. Six hybridomas were produced from three independent fusions of Balb/c spleen cells with P3-NS1-Ag 4-1 (abbreviated NS1) or X63-Ag 8.653 (X63) myeloma cells. The mice had been hyperimmunized with zeatin riboside-bovine serum albumin conjugate or dihydrozeatin riboside-bovine serum albumin conjugate for 3 months. The hybridomas secrete antibodies of the IgG 1 or IgG 2b subclass and allow the detection of femtomole amounts of the free cytokinins, their ribosides, and ribotides in plant extracts. The use of these monoclonals in radio- and enzyme-linked immunosorbent assay is also discussed.

摘要

报道了 4 种高亲和力的单克隆抗体,它们可以识别两种来自细胞分裂素组的植物生长调节剂,即玉米素核苷和二氢玉米素核苷及其衍生物。从 3 次独立融合的 Balb/c 脾细胞与 P3-NS1-Ag 4-1(简称 NS1)或 X63-Ag 8.653(X63)骨髓瘤细胞中产生了 6 株杂交瘤。这些小鼠经过 3 个月的玉米素核苷-牛血清白蛋白缀合物或二氢玉米素核苷-牛血清白蛋白缀合物的超免疫接种。杂交瘤分泌 IgG1 或 IgG2b 亚类的抗体,允许在植物提取物中检测到皮摩尔数量的游离细胞分裂素、它们的核苷和核苷酸。还讨论了这些单克隆抗体在放射免疫和酶联免疫吸附测定中的应用。
