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.

Corticosterone ELISA Kit
Corticosterone ELISA Kit

Item number: Cay501320-96

Corticosterone is a glucocorticoid produced by the adrenal cortex in response to ACTH (corticotropic hormone) and is the precursor to aldosterone. The production of glucorcorticoids is increased by stress, therefore, corticosterone can be used as a biomarker of stress. Biologists often measure corticosterone in...

Prostaglandin E2 ELISA Kit - Monoclonal
Prostaglandin E2 ELISA Kit - Monoclonal

Item number: Cay514010-480

Prostaglandin E2 (PGE2) is a primary product of arachidonic acid metabolism in many cells. Like most eicosanoids, it does not exist preformed in any cellular reservoir. When cells are activated or exogenous free arachidonate is supplied, PGE2 is synthesized de novo and released into the extracellular space. In vivo,...

6-keto Prostaglandin F1alpha ELISA Kit
6-keto Prostaglandin F1alpha ELISA Kit

Item number: Cay515211-96

Prostacyclin (Prostaglandin I2, PGI2) is formed from arachidonic acid primarily by the vascular endothelium and renal cortex. It is a potent vasodilator and inhibitor of platelet aggregation. PGI2 is non-enzymatically hydrated to 6-keto PGF1alpha (t½ = 2-3 minutes), and then quickly converted to the major...

Thromboxane B2 ELISA Kit
Thromboxane B2 ELISA Kit

Item number: Cay501020-96

Thromboxane A2 (TXA2) is produced from arachidonic acid by many cells and causes irreversible platelet aggregation and contraction of vascular and bronchial smooth muscle. Like most lipid mediators, TXA2 is not a circulating hormone. It is formed in response to local stimuli and exerts its effects within a short...
