  • 产品描述:
    小鼠β-klotho(KLB)酶联免疫试剂盒(CSB-EL012378MO)为双抗夹心法ELISA试剂盒,定量检测血清、血浆、组织匀浆样本中的KLB含量。KLB(β-Klotho)是一种跨膜蛋白,主要在肝脏和脂肪组织中表达,与FGF19结合后成为FGFR1c和FGFR4的高亲和力受体,调节胆汁酸合成和肝细胞增殖。KLB在多种代谢过程中发挥调节作用,其变异与NAFLD儿童肝损害有关,可能对肝细胞的脂毒性和炎症起保护作用。研究机制涉及FGF19-KLB-FGFRs信号通路,对理解相关疾病的发生发展具有重要意义。试剂盒检测范围为2.74 pg/mL-2000 pg/mL,可应用于代谢调控机制研究、基因敲除/过表达模型中KLB蛋白表达验证,以及药物干预或营养状态改变后体内KLB水平动态监测等科研场景。本品仅用于科研,不用于临床诊断,产品具体参数及操作步骤详见产品说明书。

  • 功能:
    Contributes to the transcriptional repression of cholesterol 7-alpha-hydroxylase (CYP7A1), the rate-limiting enzyme in bile acid synthesis. Probably inactive as a glycosidase. Increases the ability of FGFR1 and FGFR4 to bind FGF21.
