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.

11beta-Prostaglandin F2alpha ELISA Kit
11beta-Prostaglandin F2alpha ELISA Kit

Item number: Cay516521-96

Prostaglandin D2 (PGD2) is the major eicosanoid released from stimulated mast cells. PGD2 is an unstable compound which is rapidly metabolized and eliminated from the circulation. This makes quantitation of PGD2 an unreliable indicator of its in vivo production. 11beta-PGF2alpha is the primary plasma metabolite of...
