ELISA und Immunassays

Enzyme-linked Immunosorbent Assay (ELISA) ist ein biochemisches Verfahren, um das Vorhandensein eines Antikörpers oder eines Antigens in einer Probe nachzuweisen. Ein indirekter ELISA wird verwendet, um die Menge von Antikörpern gegen ein spezifisches Antigen in einer Probe zu bestimmen. Ein Sandwich-ELISA dient hingegen dazu, die Konzentration des Analyten unter Verwendung von Antikörpern, die an den Analyten (und einer Standard) binden, zu bestimmen. Eine andere Möglichkeit zur Bestimmung der Analyt-Konzentration ist ein kompetitiver ELISA, oft als EIA bezeichnet. Diese Technik wird bei kleinen Analyten bevorzugt.

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

Artikelnummer: 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,...

Artikelnummer: 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,...
