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.

Cyclic AMP ELISA Kit
Cyclic AMP ELISA Kit

Item number: Cay581001-96

Cayman's cAMP assay is a very sensitive competitive ELISA that permits cAMP measurements within the standard curve range of 0.078-10 pmol/ml, typically with a sensitivity (80% B/B0) of 0.1 pmol/ml once samples and standards have been acetylated prior to analysis. This assay has been validated with culture media,...
