腎損傷標(biāo)志物NGAL的免疫學(xué)檢測(cè)
NGAL是中性粒細(xì)胞明膠酶相關(guān)脂質(zhì)運(yùn)載蛋白,并在人體組織細(xì)胞中廣泛分布,如支氣管、胃、小腸、胰腺、腎、前列腺、胸腺等。近年研究發(fā)現(xiàn),NGAL與腎臟關(guān)系十分密切,目前有大量的實(shí)驗(yàn)和臨床研究表明,腎損傷后NGAL的表達(dá)量顯著增高并分泌到體液中,NGAL被認(rèn)為是新的早期腎損傷生化標(biāo)志物。那么,制備特異性NGAL抗體并建立相應(yīng)的NGAL免疫檢測(cè)方法非常重要。
云克隆公司原核表達(dá)了重組人NGAL蛋白(RPB388Hu01)作為抗體制備的免疫原,并制備出特異性NGAL單克?。?a >MAB388Hu22)和多克隆抗體(PAB388Hu01),同時(shí)還有標(biāo)記抗體(PAB388Hu71、PAB388Hu81)。對(duì)于這些抗體的特異性我們都有實(shí)驗(yàn)數(shù)據(jù)進(jìn)行支撐,如下圖的WB和IHC即對(duì)抗體的檢測(cè)驗(yàn)證。
在獲得特異性抗體后就需要建立NGAL免疫學(xué)檢測(cè)方法,我司應(yīng)用棋盤滴定法確定ELISA體系最佳工作條件,研發(fā)出了NGAL定量檢測(cè)ELISA試劑盒(SEB388Hu)以及CLIA試劑盒(SCB388Hu)。試劑盒SEB388Hu的線性檢測(cè)范圍0.156-10ng/mL,靈敏度達(dá)到0.069ng/ml,回收率為78%-102%,試劑盒的線性、穩(wěn)定性,批內(nèi)批間CV%都經(jīng)過(guò)反復(fù)的驗(yàn)證,產(chǎn)品可靠。其中有關(guān)NGAL檢測(cè)試劑盒的發(fā)表文獻(xiàn)就高達(dá)11篇,簡(jiǎn)要列出幾篇文獻(xiàn)見(jiàn)下表:
