Enzyme immunoassays (EIA) use the catalytic properties of enzymes to detect and quantify immunological reactions. The ELISA enzyme-linked immunosorbent assay is a heterogeneous EIA technique, Abstract. Rat LH rLH and FSH rFSH were measured by sensitive and specific competitive ELISAs. The rat LH ELISA used rLH-I plates, rLH antiserum, and peroxidase-labeled rabbit IgG antibody. Using rLH-RP-, a standard, rat LH was determined by binding of the anti-LH antibody to rLH-I-, the zodiac sign of Eliya according to Western astrology.
