Report of studies on monoclonal antibodies (MABS) to complement components
Abstract:
Twenty-five monoclonal antibodies (MABS) to complement components were evaluated according to the ISBT/ICSH protocol by twelve laboratories. Seven detected some form of C3c, but one of them, 174, did not react with EiC3b, although it was positive with 'EC3b' (Fruitstone). 174 may detect some form of enzyme sensitive C3b antigen, but C3a was not evaluated (present on 'EC3b' Fruitstone). Twelve of the antibodies were anti-C3d, one was an anti-C3g and five were anti-C4c.

Hybridoma Technology
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Antibody Actions
Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.

Complement System
The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a membrane...
