      Specification
      Sensitivity: 0.188 ng/mL (The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest protein concentration that could be differentiated from zero).
      Detection Range: 0.313–20 ng/mL
      Specificity: This kit recognizes Biotin. No significant cross-reactivity or interference was observed.
      Repeatability: Coefficient of variation is <10%.

      Test principle

      This kit uses Competitive-method. The microplate provided in this kit has been pre-coated with Biotin. During the reaction, Biotin in the sample or standard competes with a fixed amount of Biotin on the solid phase supporter for sites on the Avidin-HRP specific to Biotin. Excess Avidin-HRP and unbound sample or standard are washed from the plate. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by adding Stop Solution and the color change can be measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Biotin in samples can be calculated by comparing the OD of the samples with the standard curve.


      Calculation of results

      Average the duplicate readings for each standard and samples. Plot a four-parameter logistic curve on log-log graph paper, with standard concentration on the x-axis and OD values on the y-axis.

      If samples have been diluted, the concentration calculated from the standard curve must be multiplied by the dilution factor. If the OD of the sample surpasses the lower limit of the standard curve, you should re-test it after appropriate dilution. The actual concentration is the calculated concentration multiplied dilution factor.


      SUMMARY

      1.  Add 50 μL standard or sample to each well. 

      2.  Immediately add 50 μL Avidin-HRP to each well. 

      3.  Incubate for 30 min at 37℃

      4Aspirate and wash 5 times

      5. Add 90 μL Substrate Reagent. Incubate 15 min at 37℃

      6. Add 50 μL Stop Solution. Read at 450 nm immediately.

      7. Calculation of results
