Abstract

A solid-phase radioimmunoassay (RIA) was used for the detection and quantitation of immunoglobulin class-specific antibodies to Mycoplasma pulmonis in mouse sera. The RIA was found to be more sensitive than the single radial haemolysis (SRH) test for detecting antibodies in sera from mice at intervals after inoculation with M. pulmonis, since antibody was detected in 26 out of 29 serum samples by RIA but in only 8 out of 29 samples by SRH. A method is described for quantitating immunoglobulin class-specific antibody in test sera by reference to a standard serum. The RIA should be useful for the study of the relative importance of various immunoglobulin classes in resistance to mycoplasma infections.

摘要

采用固相放射免疫测定法(RIA)检测和定量小鼠血清中针对肺支原体的免疫球蛋白类特异性抗体。结果发现,在接种肺支原体后的不同时间间隔检测小鼠血清中的抗体时,RIA比单向辐射溶血(SRH)试验更灵敏,因为通过RIA在29份血清样本中的26份检测到了抗体,而通过SRH仅在29份样本中的8份检测到抗体。本文描述了一种通过参考标准血清来定量检测血清中免疫球蛋白类特异性抗体的方法。RIA对于研究各种免疫球蛋白类在抵抗支原体感染中的相对重要性应该是有用的。
