Abstract

The VH specificities of two rabbit antisera raised against the H chains of two human IgM cold agglutinins were studied with the aid of proteins on which the VH sequence data are available. They were found to recognize a new VH antigen (VHMar), which may represent a subgroup of VHI. This antigen is found on anti-Ii antibodies which have cross-reactive idiotypes. It is moderately well-expressed in normal gamma globulin and strongly expressed on 8% of unselected myeloma and macroglobulinaemia proteins. There is evidence to suggest that a proportion of the cross-reactive idiotypes among the anti-Ii antibodies involve this VH antigen.

摘要

借助于已有VH序列数据的蛋白质,研究了针对两种人IgM冷凝集素重链产生的两种兔抗血清的VH特异性。发现它们识别一种新的VH抗原(VHMar),它可能代表VHI的一个亚组。这种抗原存在于具有交叉反应独特型的抗Ii抗体上。它在正常丙种球蛋白中表达适中,在8%未经选择的骨髓瘤和巨球蛋白血症蛋白上强烈表达。有证据表明,抗Ii抗体中的一部分交叉反应独特型涉及这种VH抗原。
