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.

Thromboxane B2 ELISA Kit
Thromboxane B2 ELISA Kit

Artikelnummer: 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 distance of its biosynthesis. TXA2 is rapidly hydrolyzed...

11-keto Testosterone ELISA Kit
11-keto Testosterone ELISA Kit

Artikelnummer: Cay582751-96

While testosterone is the primary androgenic male steroid found in mammals, 11-keto testosterone (11-KT) is a second key androgenic steroid found in fish. It occurs in males together with testosterone in amounts which vary from less than 1 ng/ml to as much as 50-100 ng/ml, depending on the species and the stage of the reproductive cycle. In the sea bass, testosterone...

DNA/RNA Oxidative Damage ELISA Kit
DNA/RNA Oxidative Damage ELISA Kit

Artikelnummer: Cay589320-96

Both DNA and RNA are damaged by oxidation during aging and in a variety of disease states including cancer. The repair processes that are initiated to correct this damage release multiple oxidized guanine species into the urine. Cayman Chemical has developed this immunoassay for the measurement of DNA/RNA oxidative damage that detects all three oxidized guanine species,...

Prostaglandin E2 Express ELISA Kit

Artikelnummer: Cay500141-96

PGE2 is one of the primary COX products of arachidonic acid and one of the most widely investigated prostaglandins. Its activity influences inflammation, fertility and parturition, gastric mucosal integrity, and immune modulation. Because of its involvement in inflammation, PGE2 is the key indicator of non-steroidal anti-inflammatory drugs efficacy via inhibition of COX-1...

Cortisol ELISA Kit
Cortisol ELISA Kit

Artikelnummer: Cay500360-96

Cortisol is a glucocorticoid produced by the adrenal cortex in response to adrenocorticotropic hormone (ACTH). It is secreted with a circadian periodicity, and peaks just prior to waking in the morning. Cortisol is often elevated in major depressive disorder, certain forms of hypertension, stress, AIDS, and in the visceral fat of obese individuals. Cortisol can be measured...

Cortisol Express ELISA Kit

Artikelnummer: Cay500370-96S

Cayman's Cortisol Express ELISA is a competitive assay that permits the rapid measurement of cortisol from biological samples, requiring only a two hour incubation and one hour development times. This ELISA offers the convenience of a fast assay while maintaining sensitivity.NOTE: Due to an approximate 15% cross-reactivity with dexamethasone, this kit may not be suitable for...

Resolvin D1 ELISA Kit
Resolvin D1 ELISA Kit

Artikelnummer: 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 in acute inflammation. RvD1 exhibits antihyperalgesic...

Cysteinyl Leukotriene ELISA Kit

Artikelnummer: 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 bronchoconstriction, increase microvascular permeability, and are...

Oxytocin ELISA Kit

Artikelnummer: Cay500440-96

Oxytocin is a hypothalamic peptide hormone that is stored in the posterior pituitary gland. It is released into the bloodstream during parturition and lactation and is also involved in other social and sexual behaviors, neuropsyciatric disorders, and the maintenance of water and sodium homeostasis. Cayman's Oxytocin ELISA Kit is a competitive assay that can be used for...
