產品詳情

  • 產品描述：
    人細胞外基質磷酸糖蛋白(MEPE)酶聯免疫試劑盒（CSB-E09173h）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MEPE含量。MEPE（基質細胞外磷酸糖蛋白）是一種由MEPE基因編碼的蛋白質，屬于SIBLING蛋白家族，參與骨骼和牙質細胞外基質的構成與骨礦化調節。其研究機制涉及成骨細胞表達、受1,25-(OH)2D3調節，并在牙齒和骨骼發育中發揮重要作用。試劑盒檢測范圍為15.6 ng/mL-1000 ng/mL，適用于體外研究MEPE在骨代謝疾病模型中的表達調控、礦化相關信號通路機制探索，或評估不同處理條件下（如藥物干預、基因修飾）生物樣本中MEPE的濃度變化，為骨生物學、礦物質代謝等領域的科研工作提供可靠工具。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。

  • 功能：
    Promotes renal phosphate excretion and inhibits intestinal phosphate absorption. Promotes bone mineralization by osteoblasts and cartilage mineralization by chondrocytes. Regulates the mineralization of the extracellular matrix of the craniofacial complex, such as teeth, bone and cartilage. Promotes dental pulp stem cell proliferation and differentiation.
