Abstract

A quantitative assay employing (125)I-labeled antibody has been developed for Bacillus cereus T spore coat protein. Populations of antibody molecules with various affinities for inner or outer coat can be prepared by selective adsorption to and elution from different coat preparations. Adsorption to and elution from intact spores results in an antibody preparation at least 15 times more reactive to outer coat. This antibody is useful for measuring the time and extent of spore coat maturation, i.e., outer spore coat formation. Rifampin inhibits the increase in content of this coat antigen.

摘要

已开发出一种使用(125)I标记抗体的定量测定法来检测蜡样芽孢杆菌T芽孢衣壳蛋白。通过对不同衣壳制剂进行选择性吸附和洗脱,可以制备出对内衣壳或外衣壳具有不同亲和力的抗体分子群体。对完整孢子进行吸附和洗脱后得到的抗体制剂对外衣壳的反应性至少高15倍。这种抗体可用于测量芽孢衣壳成熟的时间和程度,即外芽孢衣壳的形成。利福平会抑制这种衣壳抗原含量的增加。
