  • 介紹

    FGF21 是一種主要在肝臟中產生的代謝激素。它通過多種組織中的多效作用調節葡萄糖和脂質代謝,並在各種壓力下防止代謝損傷。
     在人類中,高循環 FGF21 水平存在於肥胖和多種心臟代謝疾病中, 包括代謝綜合徵、2型糖尿病、非酒精性脂肪肝和冠狀動脈疾病。血清 FGF21 是這些疾病早期檢測和風險預測的潛在生物標誌物。

  • 測定原理

    該測定是定量夾心ELISA。免疫板預先塗有對人 FGF-21 具有特異性的兔多克隆抗體。標準品和样品被吸入孔中,任何存在的人 FGF-21 都被固定的抗體結合。洗去任何未結合的物質後,將生物素標記的特異於人 FGF-21 的多克隆抗體添加到孔中。在去除任何未結合試劑的洗滌步驟後,加入鏈黴親和素-HRP 偶聯物 (STP-HRP)。在最後一個洗滌步驟後,加入 HRP 底物溶液,顏色與最初結合的人 FGF-21 的量成比例。 停止測定並使用酶標儀測定孔的光密度。由於吸光度的增加與捕獲的人 FGF-21 的量成正比,因此可以從每個分析中包含的參考曲線中插入未知樣品濃度。
