  • 产品描述:
    CUSABIO鸡免疫球蛋白A(IgA)酶联免疫检测试剂盒(货号:CSB-E11232Ch),适用于血清、血浆样本中IgA的定量分析。IgA是禽类黏膜免疫系统的重要效应分子,广泛参与呼吸道、消化道等黏膜表面的病原体防御,其浓度变化可反映鸡体免疫状态及感染应答水平。试剂盒基于竞争法检测原理,通过预包被特异性抗体实现靶标捕获,检测灵敏度为781.25 ng/mL,线性范围覆盖781.25-50,000 ng/mL,满足科研场景中广谱浓度检测需求。实验操作需使用10μL样本量,样本可在2-8℃保存24小时或-20℃长期保存,反复冻融不超过3次。该试剂盒适用于家禽免疫学研究,如评估疫苗免疫效果、监测传染性疾病(如新城疫、禽流感)感染后的抗体动态变化,亦可用于营养免疫学实验中饲料添加剂对黏膜免疫功能的调控研究。试剂盒配套提供标准品、检测抗体及显色底物,96孔板规格支持批量样本检测,实验全程约需3.5小时完成。

  • 本试剂盒所含材料:
    • A 96-well Assay plate --The 96-well plate has been pre-coated with chicken IgA.
    • Standard(10 x concentrate) (1 x 200 μl) --Dilute the standard at dilution series, read the OD values, and then draw a standard curve.
    • HRP-conjugated IgA antibody(100 x concentrate) (1 x 60 μl) --Bind to the IgA, and HRP catalyzes the TMB to elicit a chromogenic reaction.
    • HRP-conjugate Diluent (1 x 10 ml) --Dilute the HRP-conjugated IgA antibody solution.
    • Sample Diluent (2 x 20 ml) --Reconstitute the standard and dilute the sample to an appropriate concentration.
    • Wash Buffer (25x concentrate) (1 x 20 ml) --Wash away unbound or free substances.
    • TMB Substrate (1x 10 ml) --Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
    • Stop Solution (1 x 10ml) --Stop the color reaction. The solution color immediately turns from blue to yellow.
    • Four Adhesive Strips (For 96 wells)
    • An Instruction manual

Q:

For the kit CSB-E11232Ch, a customer asks if they have been tested with tissue samples, specifically small intestine.
Would you have this information available to share?

A:
Thanks for your inquiry.
We suggest you do a pretest if you want to test small intestine.Pls let me know if you have any further questions. Thank you.
