    • 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.
    • 线性度:
      To assess the linearity of the assay, samples were spiked with high concentrations of human β-defensins 2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

    • 本试剂盒所含材料:
      • A micro ELISA plate --- The 96-well plate has been pre-coated with an anti-human DEFB4 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 DEFB4 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.
