Abstract

Polyclonal IgM obtained by fractionation of a BALB/c serum pool was used as the immunogen for C57BL/6 mice. Draining lymph nodes from selected animals donated cells for fusion with myeloma Sp-2/0. Fifteen hybridomas were productive, and one (RS-3.1) was cloned and the affinity-purified product analyzed for its reactivity pattern by MOPC 104E-enzyme-linked immunosorbent assay inhibition. Among five BALB/c myelomas only TEPC 183 (IgM) was active, not those belonging to other Ig classes. Among normal sera from 8 mouse strains only those of BALB/c, DBA/2J and CBA/J showed inhibition. The recombinant strain BALB-Igh-Va/Igh-Cb did not react, which shows that its C mu stems from parental strain C57BL/6, and that therefore the recombination event had occurred 5' of this gene.

摘要

通过对BALB/c血清库进行分级分离获得的多克隆IgM被用作C57BL/6小鼠的免疫原。从选定动物的引流淋巴结中获取细胞,用于与骨髓瘤Sp-2/0融合。15个杂交瘤具有生产能力,其中一个(RS-3.1)被克隆,并通过MOPC 104E酶联免疫吸附测定抑制法对亲和纯化产物的反应模式进行分析。在5种BALB/c骨髓瘤中,只有TEPC 183(IgM)具有活性,其他Ig类别的骨髓瘤则无活性。在8种小鼠品系的正常血清中,只有BALB/c、DBA/2J和CBA/J的血清表现出抑制作用。重组品系BALB-Igh-Va/Igh-Cb没有反应,这表明其Cμ基因来源于亲本品系C57BL/6,因此重组事件发生在该基因的5'端。
