產品詳情

  • 產品描述:
    人溶血磷脂酸(LPA)酶聯免疫試劑盒(CSB-EQ028005HU)為競爭法ELISA試劑盒,定量檢測血清、血漿、組織勻漿樣本中的LPA含量。LPA(溶血磷脂酸)是一種生物活性磷脂介質,在體內參與多種生物學過程,如細胞增殖、分化、凋亡和遷移等。其研究機制涉及通過LPA受體激活多條信號通路,影響細胞功能。LPA在腫瘤、心血管疾病和骨組織工程等領域具有潛在應用價值。試劑盒檢測范圍為3.9 ng/mL-250 ng/mL,適用于基礎研究中LPA代謝通路的動態監測、疾病模型中的生物標志物探索以及藥物干預實驗的效果評估。尤其適合細胞培養上清、動物模型組織等復雜基質中LPA的定量分析,為脂質介導的信號傳導機制研究提供可靠工具。本品僅用于科研,不用于臨床診斷,產品具體參數及操作步驟詳見產品說明書。

  • 本試劑盒所含材料:
    • A 96-well Assay plate --The 96-well plate has been pre-coated with human LPA.
    • 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 LPA antibody(100 x concentrate) (1 x 60 μl) --Bind to the LPAA, and HRP catalyzes the TMB to elicit a chromogenic reaction.
    • HRP-conjugate Diluent (1 x 10 ml) --Dilute the HRP-conjugated LPAantibody 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:

I want to know wihich type of plastic plates are included in this elisa kit to evaluate our optical density.

A:
Thanks for your inquiry!
The plate of our kit CSB-EQ028005HU is with 8 wells× 12 strips.
Pls just use the general microplate reader with the 450nm wavelength.
Any question, pls feel free to contact me.
Q:

CSB-EQ028005HU? - Human lysophosphatidic acid (LPA) Elisa kit Knowing that LPA is also found in mice, do you think it will also work for mice cells?

A:
Thanks for your inquiry! This kit is specific to human. For different species there is matrix difference, so we don't suggest you use this kit to test mouse samples.
