产品详情

  • 产品描述:
    人血管紧张素Ⅱ(ANG-Ⅱ)酶联免疫试剂盒(货号:CSB-E04493h)采用竞争法定量检测血清或血浆样本中的ANG-Ⅱ水平,检测灵敏度覆盖31.25 pg/ml至2000 pg/ml的浓度范围。ANG-Ⅱ是肾素-血管紧张素系统(RAS)的核心效应分子,通过调节血管收缩、醛固酮分泌及细胞增殖等生理过程参与高血压、心血管疾病及肾脏功能异常的病理机制研究。本试剂盒基于抗原抗体特异性结合原理,通过标准品与样本中ANG-Ⅱ竞争结合标记抗体实现精确定量,适用于科研场景中探究ANG-Ⅱ在心血管疾病模型中的动态变化、药物干预效果评估或相关代谢调控机制分析。操作流程兼容常规实验室设备,支持批量样本的高通量检测,为心血管疾病基础研究、药理学实验及生物标志物探索提供可靠工具。试剂盒组分包含预包被板、标准品、检测抗体及显色底物,需自备酶标仪(450 nm波长)完成读数。

  • 本试剂盒所含材料:
      • A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human ANG-II antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
      • Two vials lyophilized standard --- Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
      • One vial Biotin-labeled ANG-II antibody (100 x concentrate) (120 μl/bottle) ---Act as the detection antibody.
      • One vial HRP-avidin (100 x concentrate) (120 μl/bottle) --- Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
      • One vial Biotin-antibody Diluent (15 ml/bottle) ---Dilute the Biotin-antibody.
      • One vial HRP-avidin Diluent (15 ml/bottle) ---Dilute the HRP-avidin solution.
      • One vial Sample Diluent (50 ml/bottle)---Dilute the sample to an appropriate concentration.
      • One vial Wash Buffer (25 x concentrate) (20 ml/bottle) --- Wash away unbound or free substances.
      • One vial TMB Substrate (10 ml/bottle) --- Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
      • One vial Stop Solution (10 ml/bottle) --- Stop the color reaction. The solution color immediately turns from blue to yellow.
      • Four Adhesive Strips (For 96 wells) --- Cover the microplate when incubation.
      • An instruction manual
