被动皮肤过敏试验(简称PCA试验)是一种较佳的鉴定抗原抗体反应的体内法,可测定特异性抗体及抗体滴度,并可鉴定抗体类型。本文应用PCA试验对工业化学物乙二胺致敏动物体内特异性抗体进行了分析。乙二胺半抗原和全抗原致敏的
Passive skin allergy test (referred to as PCA test) is a better in vivo method of identification of antigen-antibody reaction, which can determine the specific antibody and antibody titers, and can identify the type of antibody. In this paper, the PCA assay was used to analyze the specific antibodies in the industrial chemical ethylenediamine sensitized animals. Ethylenediamine haptens and whole antigen sensitized
