產品描述：

大鼠細胞角蛋白18-M65（CK 18-M65）酶聯免疫試劑盒（CSB-EQ027319RA）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KRT18含量。KRT18 是角蛋白家族成員。在細胞中維持細胞結構穩定、參與信號傳導。其異常表達與腫瘤等疾病密切相關。研究發現它可作為腫瘤診斷標志物，還參與腫瘤細胞增殖、遷移等過程，有望成為潛在治療靶點。試劑盒檢測范圍為0.94 ng/mL-60 ng/mL，適用于科研領域中對大鼠模型的組織病理機制研究，例如肝纖維化、肝癌模型構建或化學誘導毒性實驗中細胞死亡動態監測，為評估上皮細胞損傷程度及疾病進展提供定量分析工具。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：

When phosphorylated, plays a role in filament reorganization. Involved in the delivery of mutated CFTR to the plasma membrane. Together with KRT8, is involved in interleukin-6 (IL-6)-mediated barrier protection. Involved in the uptake of thrombin-antithrombin complexes by hepatic cells.
