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.

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

Item number: Cay514010-96

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,...

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...

Leukotriene B4 ELISA Kit
Leukotriene B4 ELISA Kit

Item number: Cay520111-96

Leukotriene B4 (LTB4) is synthesized from arachidonic acid by the combined action of 5-lipoxygenase and LTA4 hydrolase. LTB4 has long been recognized as a potent mediator of inflammation. It stimulates a number of leukocyte functions, including aggregation, stimulation of ion fluxes, enhancement of lysosomal enzyme...
