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.

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...

Resolvin D1 ELISA Kit
Resolvin D1 ELISA Kit

Item number: Cay500380-96

Resolvin D1 (RvD1) is produced physiologically from the sequential oxygenation of DHA by 15- and 5-lipoxygenases. The 17(R)-epimer of RvD1 can also be generated with aspirin-treatment. Both RvD1 and its 17(R) configuration reduce human polymorphonuclear leukocyte (PMNL) transendothelial migration, the earliest event...

Cysteinyl Leukotriene ELISA Kit
Cysteinyl Leukotriene ELISA Kit

Item number: Cay500390-96

Leukotrienes (LTs) are a group of acute inflammatory mediators derived from arachidonic acid via the 5-lipoxygenase (5-LO) pathway in leukocytes. LTC4, LTD4, and LTE4 are collectively referred to as cysteinyl leukotrienes (CysLTs). LTC4 and LTD4 are potent mediators of asthma and hypersensitivity. They induce...
