产品详情

  • 产品描述:
    人缺血修饰白蛋白(IMA)是心肌缺血早期病理过程中产生的特异性生物标志物,其水平变化与组织缺氧损伤密切相关,在心血管疾病机制研究和药物开发评价中具有重要科研价值。本试剂盒(货号:CSB-E09594h)采用双抗体夹心酶联免疫吸附法(Sandwich ELISA),专为定量检测血清、血浆及组织匀浆样本中的IMA含量而设计,覆盖3.12 IU/mL至200 IU/mL的线性检测范围,灵敏度达3.12 IU/mL,可精准捕捉低浓度靶标。实验操作基于预包被特异性抗体的微孔板,通过生物素标记检测抗体与链霉亲和素-HRP系统的级联反应实现信号放大,配合标准曲线完成定量分析。该试剂盒适用于心血管疾病动物模型研究、缺血再灌注损伤机制探索、药物干预效果评估等科研场景,配套提供标准品、检测抗体及优化缓冲液体系,支持多样本类型的高通量检测。建议实验前对组织样本进行充分匀浆及离心处理,血浆样本需使用EDTA或肝素抗凝管采集,避免反复冻融以保证检测准确性。

  • 本试剂盒所含材料:
    • A micro ELISA plate ---The 96-well plate has been pre-coated with an anti-Human IMA antibody.
    • 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 IMA 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 incubating.
