  • 產品描述：
    小鼠P選擇素(P-Selectin/CD62P)酶聯免疫試劑盒（CSB-E04709m）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SELP含量。SELP（選擇素P）是一種細胞表面糖蛋白，參與調節免疫細胞粘附和遷移。研究顯示，SELP在多種癌癥中表達升高，可能作為治療靶點。其研究機制涉及SELP與免疫細胞相互作用，影響腫瘤微環境，從而促進腫瘤生長和轉移。抑制SELP表達可能有助于抑制腫瘤發展。試劑盒檢測范圍為31.25 pg/mL-2000 pg/mL，靈敏度為7.8 pg/mL。適用于體外培養細胞模型、動物疾病模型（如動脈粥樣硬化、缺血再灌注損傷等）中P選擇素表達水平的分析，或用于評估藥物干預對血小板活化及內皮功能的影響，為科研人員探索相關疾病的分子機制提供可靠工具。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。
