CONCERNING A POLYVALENT ANTIGEN FOR THE COMPLEMENT FIXATION TEST FOR STREPTOCOCCUS VIRIDANS INFECTION
1Department of Clinical Pathology of Cornell University Medical College, and The Second Medical Division of Bellevue Hospital, New York.
Abstract:
1. Streptococcus viridans is of extremely low virulence for white mice and rabbits. 2. The serum of rabbits, after a series of intravenous injections of dead or living Streptococcus viridans, is poor in complement fixative substance (fixateur of Besredka) for Streptococcus viridans. 3. Antigens prepared from several strains of Streptococcus viridans are relatively poor in fixable substance. 4. The technique of complement fixation tests for infection with Streptococcus viridans is so laborious and difficult that the method will not be available for general clinical work.

There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
