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.

Leukotriene E4 ELISA Kit
Leukotriene E4 ELISA Kit

Item number: Cay501060-96

Leukotriene E4 (LTE4) is a product of the 5-lipoxygenase (5-LO) pathway in activated mast cells, eosinophils, and monocytes. LTA4, the primary 5-LO metabolite, is rapidly converted to LTC4 and sequentially to LTD4 and LTE4. While plasma levels of LTC4 are virtually undetectable, exogenously administered LTC4 is...

Aldosterone ELISA Kit
Aldosterone ELISA Kit

Item number: Cay501090-96

Aldosterone, a steroid hormone secreted by the adrenal cortex, is the principle mineralocorticoid controlling sodium and potassium balance. Serum aldosterone levels in normal upright adult individuals are generally less than 300 pg/ml. Only a fraction of urinary aldosterone is excreted intact, thus urinary excretion...

Maresin 1 ELISA Kit
Maresin 1 ELISA Kit

Item number: Cay501150-96

Maresins (macrophage mediators in resolving inflammation) are members of a class of potent anti-inflammatory and pro-resolving mediators that are synthesized by macrophages in the presence of docosahexaenoic acid (DHA). Maresin 1 (MaR1) is produced via oxidation of endogenous DHA by 12-lipoxygenase. MaR1 has been...

Corticosterone ELISA Kit
Corticosterone ELISA Kit

Item number: Cay501320-480S

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...

Item number: Cay501420-96

11-Oxoetiocholanolone is a metabolite of cortisol that is found in the feces of ungulates and other animals. Stress-induced glucocorticoids (cortisol, corticosterone) traditionally have been measured through blood sampling, but the collection process is known to cause stress in animals, interfering with experimental...

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,...
