An immunoglobulin heavy chain variable region (VH) marker associated with cross-reactive idiotypes in man. 1977

T Feizi, and J Lecomte, and R Childs

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.

D007135	Immunoglobulin Variable Region	That region of the immunoglobulin molecule that varies in its amino acid sequence and composition, and comprises the binding site for a specific antigen. It is located at the N-terminus of the Fab fragment of the immunoglobulin. It includes hypervariable regions (COMPLEMENTARITY DETERMINING REGIONS) and framework regions.
