Abstract
This invention relates to improved 'sandwich' immunoassays for antibodies in body fluids of the type where antigen specific for the antibody to be detected is disposed on a solid support and binds antibody from the body fluid, from which the antibody bound to the solid support is detected by a labeled antigen to the antibody to be detected. The improvement comprises using antigens from heterologous cell sources.
