Abstract:
In order to produce macaque monoclonal antibodies (mAbs) against human red blood cell (RBC) antigens, macaques were immunized with human and gorilla RBCs and their spleen lymphocytes were fused with man-mouse heteromyeloma cells. One macaque-mouse heterohybridoma produced a macaque IgGx (Cvn2-4D5) which agglutinated all human RBCs but not rare human variants Dc-,D-, and Rhnull. Thus, Cyn2-4D5 exhibited RH17-like reactivity. The specificity of Cyn2-4D5 for RHCE-encoded polypeptides was confirmed by specific immunoprecipitation of RhcE and RhCe polypeptides from human RBCs and the absence of immunoprecipitation of the RhD polypeptides extracted from D-RBCs. This study demonstrates that it is possible to produce macaque mAbs against human RBC blood group antigens.

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.
