產品詳情

  • 產品描述：
    人脊椎蛋白-1(SPON1)酶聯免疫試劑盒（CSB-EL022599HU）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SPON1含量。SPON1（脊椎蛋白-1）是一種細胞外基質結構成分，參與細胞粘附和蛋白質結合活性的調節。其研究機制涉及在細胞外空間與膠原蛋白共定位，并可能參與淀粉樣蛋白前體蛋白的分解代謝過程。在疾病如阿爾茨海默病中，SPON1的表達和功能可能發生變化，影響疾病的發病機制。試劑盒檢測范圍為0.156 ng/mL-10 ng/mL，科研人員可通過探究SPON1在神經退行性疾病模型中的表達特征，分析其在腫瘤微環境中的調控作用，或評估骨骼發育相關疾病中該蛋白的生物標志物價值；適用于體外實驗中的基礎機制研究、疾病模型分析及生物標志物篩選等科研場景，為探索SPON1的分子功能及其在病理生理過程中的作用提供可靠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：
    Cell adhesion protein that promotes the attachment of spinal cord and sensory neuron cells and the outgrowth of neurites in vitro. May contribute to the growth and guidance of axons in both the spinal cord and the PNS. Major factor for vascular smooth muscle cell.
