ELISA and Immunoassays

Enzyme-linked immunosorbent assay (ELISA) is a biochemical technique to detect the presence of an antibody or an antigen in a sample. Whereas an indirect ELISA is used to determine the amount of antibodies to a specific antigen in a sample, a Sandwich-ELISA is used to determine the concentration of the analyte by use of antibodies that bind to the analyte (and a standard). A different way of determining the analyte concentration is a competitive ELISA, often called EIA. This technique is preferred for small analytes.

Prostaglandin D2-MOX ELISA Kit
Prostaglandin D2-MOX ELISA Kit

Item number: Cay512011-96

Prostaglandin D2 (PGD2) is biosynthesized in the brain by a soluble, 26 kD glutathione-independent lipocalin-type PGD2 synthase. PGD2 accumulates in the cerebrospinal fluid (CSF), where it induces physiologic sleep in rats and humans. PGD2 is also synthesized by mast cells and leukocytes by a cellular, myeloid-type,...
