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

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
