Abstract:
An antigen isolated from Neisseria gonorrhoeae protoplasm reacted well in a flocculation procedure with sera from 86% of the females and 68% of the males infected with gonorrhea; the reactions with sera from presumed noninfected individuals were approximately 12%.

01:26Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
