This competitive ELISA kit is for determination of 12-HETE (12-Hydroxyeicosatetraenoic acid) levels in biological samples. The specificity of the 12-HETE ELISA was investigated using authentic 12-HETE ａnd fatty acids which, based on their structure, might be anticipated to compete with 12-HETE for binding to antibodies against 12-HETE.

HETEs are byproducts generated by the metabolism of arachidonic acid by lipoxygenases. 12(S)-HETE is the stereospecific hydroxyl product produced from the reduction of 12(S)-hydroperoxytetraenoic eicosatetraenoic acid [12(S)-HpETE], which is itself is a 12-lipoxygenase metabolite of arachidonic acid. It has recently been reported that platelet 12(S)-HETE production is enhanced in the spontaneously hypertensive rat1. 12(S)-HETE levels ａnd 12-lipoxygenase (12-LO) protein are increased in patients with essential hypertension2, also suggesting a role for this

metabolite in human hypertension. These metabolites exhibit a variety of biological activities such as mediation of angiotensin II–induced intracellular calcium transients in cultured rat vascular smooth muscle cells3 ａnd as a second messenger in angiotensin-II induced aldosterone production4

. 12(S)-HETE also acts as an aggregator of polymorphonuclear leukocytes5 ａnd is a highly selective ligand used to label mu opioid receptors6 ａnd serves as a biomarker of Churg-Strauss syndrome7.

Each kit can be used for triplicate analyses of up to 24 samples contains using a 96 well plate format, ａnd contains a vial of 12-HETE standard, a vial of 12-HETE-conjugated horseradish peroxidase (HRP), ａnd buffers for sample ａnd HRP dilutions, ａnd plate washing.

這種競爭性ELISA試劑盒用于測定生物中12-HETE（12-羥基二十碳四烯酸）的水平樣品。使用真實的12-HETE和脂肪酸研究12-HETE ELISA的特異性可以預期在其結構上與12-HETE競爭與針對12-HETE的抗體的結合�？�-12-HETE僅與15-HETE和13-HODE輕微交叉反應。

HETE是花生四烯酸通過脂氧合酶代謝產生的副產物。

12（S）-HETE是12-（S）-氫過氧四烯酸二十碳四烯酸還原產生的立體特異性羥基產物[12（S）-HpETE]，其本身是花生四烯酸的12-脂氧合酶代謝產物。近有報道稱自發性高血壓大鼠血小板12（S）-HETE的產生增強1.12（S）-HETE水平和12-原發性高血壓患者脂氧合酶（12-LO）蛋白增加2，也暗示了這方面的作用人類高血壓的代謝產物。這些代謝產物表現出多種生物活性，如介導血管緊張素II誘導的培養大鼠血管平滑肌細胞內鈣瞬變3作為第二個血管緊張素II誘導的醛固酮產生中的信使4.12（S）-HETE還充當多形核白細胞5是一種用于標記μ阿片受體的高選擇性配體6并作為丘格-斯特勞斯綜合征的生物標志物7.

每個試劑盒可用于對多達24個樣品進行一式三份的分析，包含使用96孔板格式的樣品，并包含一個小瓶12-HETE標準，一小瓶12-HETE綴合的辣根過氧化物酶（HRP），以及用于樣品和HRP的緩沖液稀釋和板洗滌。
