产品详情

  • 产品描述:
    CUSABIO人补体片断3a(C3a)酶联免疫试剂盒(货号:CSB-E08509h),采用夹心法原理实现定量检测,适用于分析血清、血浆及组织匀浆样本中C3a的浓度。C3a是补体系统活化过程中产生的关键炎症介质,参与调节过敏反应、趋化免疫细胞及介导组织炎症反应,其水平变化与多种免疫性疾病和炎症状态密切相关。该试剂盒检测范围为31.25-2000 ng/mL,通过双抗体夹心技术实现高特异性检测:预包被于微孔板的捕获抗体与样本中C3a结合后,再通过酶标检测抗体形成复合物,最终显色强度与目标物浓度呈正相关。本产品适用于科研领域中对补体系统激活机制的研究,如炎症性疾病动物模型评估、免疫调控通路探索或药物干预效果分析等场景,为体外实验提供灵敏、稳定的检测方案。试剂盒包含标准品、检测抗体、显色底物等核心组分,操作流程标准化,支持实验室高效开展C3a相关基础研究。

  • 本试剂盒所含材料:
    • A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human C3a 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 C3a 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.
