產品詳情

  • 產品描述：
    人前動力蛋白2(PROK2)酶聯免疫試劑盒（CSB-EL018747HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織培養上清液、組織勻漿樣本中的PROK2含量。PROK2即促動素2，是分泌性蛋白。其作為重要靶點，在人體生理活動如血管生成、神經發育等方面發揮作用。研究機制方面，它主要通過與特定受體結合，激活下游信號通路，進而影響細胞行為，目前在腫瘤、神經系統疾病等研究中受關注。試劑盒檢測范圍為6.25 pg/mL-400 pg/mL，該產品可為科研人員提供可靠工具，用于探索PROK2在生殖生物學、腫瘤發生機制或神經內分泌調控中的功能，亦可用于評估細胞模型、動物組織或生物體液中的蛋白表達水平變化，為相關疾病的分子機制研究及藥物開發提供數據支持。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    May function as an output molecule from the suprachiasmatic nucleus (SCN) that transmits behavioral circadian rhythm. May also function locally within the SCN to synchronize output. Potently contracts gastrointestinal (GI) smooth muscle.
