血管緊張素是來(lái)源于血管緊張素原的小肽。幾種已知的血管緊張素是調(diào)節(jié)血壓的既定內(nèi)分泌效應(yīng)物，但它們也已知在一些器官和組織（旁分泌）和細(xì)胞水平（自分泌/內(nèi)分泌）具有其他局部功能。血管緊張素I(DRVYIHPFHL)沒(méi)有已知的效應(yīng)器功能，但它是血管緊張素II(DRVYIHPF)的直接前體。血管緊張素II與AT1受體結(jié)合，促進(jìn)血管收縮、鈉潴留、醛固酮的釋放、氬加壓素的釋放、細(xì)胞增生、炎癥、纖維化、焦慮和心臟肥大。血管緊張素A(ARVYIHPF)，和血管緊張素III(RVYIHPF)，也與AT1受體結(jié)合。血管緊張素(1-7)(DRVYIHP)結(jié)合不同的受體，稱(chēng)為MAS-1，具有相反的作用（血管擴(kuò)張、利尿、抗擴(kuò)散、NO釋放、PGE釋放和細(xì)胞凋亡）。血管緊張素IV(VYIHPF)與另一個(gè)稱(chēng)為AT4(IRAP)的受體結(jié)合，促進(jìn)血流增加、血管生成和利尿，它也與記憶的形成和阿爾茨海默病的發(fā)病機(jī)制有關(guān)。肽LVV-hemorphin-7（LVVYPWTQRF）不是血管緊張素，但也能與AT4受體結(jié)合。還有其他已經(jīng)確定的血管緊張素肽，包括Ang(1-9)(DRVYIHPFH)、Ang(1-12)(DRVYIHPFHLVI)、Ang V(3-7)(VYIHP)，以及其他幾種功能未定的短肽。

ENZO Angiotensin II ELISA kit是一種比色競(jìng)爭(zhēng)法免疫檢測(cè)試劑盒，3.5小時(shí)內(nèi)即可得到結(jié)果。

● 高度特異性，與類(lèi)似肽交叉反應(yīng)性低

● 超越半定量Western blot分析的全定量檢測(cè)

● 易于使用的液體顏色編碼試劑，最大限度地減少錯(cuò)誤

● 即用型試劑和預(yù)包被板可減少錯(cuò)誤并節(jié)省您的時(shí)間
