產品詳情

  • 產品描述：
    大鼠胰島素樣生長因子結合蛋白2(IGFBP-2)酶聯免疫試劑盒（CSB-E07351r）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的IGFBP2含量。IGFBP2（胰島素樣生長因子結合蛋白2）是一種高親和力結合蛋白，在中樞神經系統的IGF（胰島素樣生長因子）調節中發揮重要作用。研究發現，IGFBP2在膠質瘤的發生、發展及預后中具有重要作用，其通過IGF依賴/非依賴通路、β-catenin通路等多種信號通路參與調節膠質瘤細胞的增殖、侵襲、轉移及血管生成等生理過程。試劑盒檢測范圍為0.625 ng/mL-40 ng/mL，適用于科研場景中探索IGFBP - 2在糖脂代謝調控、生長發育異常或腫瘤微環境中的作用機制，為研究IGF信號通路及相關疾病模型提供靈敏可靠的檢測工具。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：
    Inhibits IGF-mediated growth and developmental rates. IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors.
