產品詳情

  • 產品描述:
    人維生素B12(VB12)酶聯免疫試劑盒(CSB-E07903h)為競爭法ELISA試劑盒,定量檢測血清、血漿樣本中的VB12含量。VB12即維生素B12,是人體必需的水溶性維生素。它參與神經系統發育、造血等重要生理過程。研究機制上,它作為輔酶參與甲基轉移反應和L-甲基丙二酰輔酶A異構化反應,缺乏VB12會導致巨幼細胞貧血、神經系統損害等疾病。試劑盒檢測范圍為1.56 pg/mL-100 pg/mL,靈敏度為1.498 pg/mL。適用于細胞培養、動物模型或生物樣本中的VB12動態監測,支持營養干預研究、代謝性疾病機制探索及藥物開發中的生物標志物分析。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。

  • 測定方法:
    Competitive
  • 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 VB12 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

     

  • 標準曲線:

     

    These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

     

  • 本試劑盒所含材料:
      • A 96-well Assay plate --The 96-well plate has been pre-coated with anti-human VB12 antibody.
      • Standard (2 x 0.5 ml)--Dilute the standard at dilution series, read the OD values, and then draw a standard curve.
      • Biotin-conjugated VB12(100 x concentrate) (1 x 600 μl)
      • HRP-avidin (100 x concentrate) (1 x 120 μl)
      • Biotin-conjugate Diluent (1 x 10 ml) --Dilute the Biotin-conjugated VB12
      • HRP-avidin Diluent (1 x 20 ml) --Dilute the HRP-avidin 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

 常見問題解答
Q:

Protocol P9, step 3 - Set a Blank well without any solution.
This is a completely empty well with no solution or liquid at all? Am I correct?
May I know if this is S0. If it is S0, do we add the wash buffer, TMB and stop solution?

A:
Thanks for your inquiry.
Actually step3 is just only one procedure during the whole experiment. You need to check the full steps according our manual.
This kit is competitive one and the blank is different from S0 indeed. The blank should be added Wash Buffer+TMB Substrate+Stop Solution.
You could see it from the protocol. Pls read the manual carefully.
