產品詳情

  • 產品描述：
    人高半胱氨酸(Hcy)酶聯免疫試劑盒（CSB-E13814h）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、尿液、組織勻漿樣本中的Hcy含量。Hcy即同型半胱氨酸，是蛋氨酸代謝過程中產生的中間產物。高Hcy水平被視為多種疾病的獨立危險因素，如心血管疾病、神經系統疾病等。其研究機制主要圍繞其引發血管損傷、氧化應激、干擾細胞正常代謝等方面展開。試劑盒檢測范圍為0.78 nmol/mL-50 nmol/mL，可廣泛應用于基礎醫學研究中Hcy代謝通路分析、疾病機制探索（如動脈粥樣硬化、阿爾茨海默病模型研究）以及營養干預或藥物開發的療效評估，為科研人員提供高效、穩定的Hcy濃度檢測方案。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。
  • 別名：
    N/A
  • 縮寫：
    Hcy

    50-100ul
  • 檢測波長：
    450 nm
  • 研究領域：
    Metabolism
  • 測定原理：
    quantitative
  • 測定方法：
    Sandwich
  • 精密度：
    Intra-assay Precision (Precision within an assay): CV%<8%
    Three samples of known concentration were tested twenty times on one plate to assess.
    Inter-assay Precision (Precision between assays): CV%<10%
    Three samples of known concentration were tested in twenty assays to assess.
  • 線性度：
    To assess the linearity of the assay, samples were spiked with high concentrations of human HCY in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

  • 本試劑盒所含材料：
    • A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human HCY 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 HCY 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-antibodyDiluent (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.
