產品詳情

  • 產品描述：
    小鼠封閉蛋白5(CLDN5)酶聯免疫試劑盒（CSB-EL005507MO）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿、細胞裂解物樣本中的CLDN5含量。CLDN5即閉合蛋白5，是緊密連接蛋白家族成員，在血管內皮細胞廣泛表達，對維持血腦屏障完整性至關重要。研究發現其可作為腫瘤治療靶點，通過調節其表達或功能，影響腫瘤血管生成和轉移，為腫瘤診斷與治療提供新思路。試劑盒檢測范圍為18.75 pg/mL-1200 pg/mL，本試劑盒通過特異性捕獲抗體與檢測抗體的協同作用，可實現目標蛋白的高效識別與定量分析，適用于生命科學研究中探索CLDN5在組織屏障功能調控、疾病模型建立、藥物干預效果評估等領域的表達變化規律。為研究者提供了一種穩定、可靠的檢測工具，適用于體外實驗模型中CLDN5蛋白水平的動態監測及相關分子機制研究。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。
