  • 產(chǎn)品描述：
    人蛋白S(Protein S)酶聯(lián)免疫試劑盒（CSB-E09903h）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PROS1含量。PROS1 是重要靶點。它與凝血和天然免疫調節(jié)等生理過程密切相關。研究機制主要聚焦于其在凝血級聯(lián)反應中的作用，通過與相關蛋白相互作用調節(jié)凝血酶生成，還涉及在炎癥反應中的調控機制，為血栓性疾病等治療提供思路。試劑盒檢測范圍為3.12 ng/mL-200 ng/mL，適用于基礎科研中蛋白S表達水平的定量分析，例如凝血機制研究、血栓相關疾病模型評估、肝臟功能研究或遺傳性蛋白S缺乏癥的分子機制探索本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。
