產(chǎn)品詳情

  • 產(chǎn)品描述：
    人胎兒纖連蛋白(fFN)酶聯(lián)免疫試劑盒（CSB-E17582h）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、尿液、組織培養(yǎng)上清液樣本中的fFN含量。fFN（胎兒纖維連接蛋白）是一種細胞外基質(zhì)糖蛋白，主要分布在羊膜母胎面，絨毛膜和蛻膜之間。在正常情況下，fFN在宮頸陰道分泌物中的水平非常低，但在妊娠22周或之后，fFN水平升高與自發(fā)早產(chǎn)風險增加相關(guān)聯(lián)。fFN檢測可用于預(yù)測早產(chǎn)風險，其研究機制主要涉及fFN在妊娠和子宮之間的“黏合劑”作用，以及其在宮頸分泌物中的水平變化。試劑盒檢測范圍為25 ng/mL-1600 ng/mL，該產(chǎn)品適用于生殖醫(yī)學(xué)領(lǐng)域的基礎(chǔ)研究，例如妊娠相關(guān)生物標志物的體外分析、胎兒發(fā)育機制探索、病理妊娠模型的蛋白表達水平評估等科研場景，也可用于體外藥物篩選或細胞模型中fFN調(diào)控機制的實驗研究，為探索妊娠期分子機制提供可靠工具。本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。
