Chicken Total Collagen (T COL) ELISA Kit DataSheet

The kit assay Chicken T COL level in the Samples, use Purified Chicken T COL antibody to coat microtiter plate wells, make solid-phase antibody, then add Samples (Containing Chicken T COL) to wells, combined Chicken T COL antidody which with HRP labeled, become antibody - antigen - enzyme-antibody complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color at HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change (yellow) is measured spectrophotometrically at a wavelength of 450 nm. The concentration of Chicken T COL in the samples is then determined by comparing the O.D. of the samples to the standard curve.

  • Can not detect the sample containing NaN3, because NaN3 inhibits the activity of HRP.

Sample Dilution Guideline
User needs to estimate the concentration of the target protein in the samples and select proper dilution factor so that the diluted target protein concentration falls near the middle of the linear regime in the standard curve.


  1. Preparation of the Standard: Set 10 Standard wells on the ELISA plates coated,label ① ② ③ ④ ⑤ ⑥ ⑦ ⑧ ⑨ ⑩ . Add Standard 100μl to ① ② , then add Standard diluent 50μl to ①②, mix ; take out 100μl from①②,and then add it to ③ ④ separately, then add Standard diluent 50μl to ③ ④ ,mix ; then take out 50μl from ③ ④ ,and discard, then take out 50μl from ③ ④ and add to ⑤ ⑥ , then add Standard diluent 50μl to the⑤⑥, mix ; take out 50μl from ⑤⑥ and add to⑦⑧, then add Standard diluent 50μl to the ⑦⑧ ,mix ; take out 50μl from the ⑦⑧ and add to ⑨⑩, add Standard diluent 50μl to⑨⑩, mix , take out 50μl from⑨⑩discard. After dilution,the total volume in each well is 50 μl,and the concentration is 90 ng/ml, 60 ng/ml, 30 ng/ml, 15 ng/ml, 7.5 ng/ml respectively.
  2. Set wells separately: Set blank well ( Please do not add Sample and HRP-Conjugate reagent to the blank comparison wells,other each step operation is same), and Testing sample well.
  3. Add Sample: Add Sample Diluent 40μl to Testing sample well, then add testing sample 10μl (Sample final dilution is 5-fold) .Please add Sample to the bottom of pre-coated well , do not touch the well wall as far as possible, and mix gently.
  4. Incubate: After closing the plate with Closure plate membrane ,incubate for 30 min at 37℃.
  5. Prepare the Washing Buffer: 30-fold Wash Solution, diluted 30-fold with Distilled water until 600ml,and reserve.
  6. Washing:Uncover Closure plate membrane, discard Liquid, dry by swing, add Washing Buffer to each well, still for 30s then drain, repeat 5 times, dry by pat.
  7. Add enzyme:Add HRP-Conjugate Reagent 50μl to each well, except the Blank well.
  8. Incubate:Operation with 4).
  9. Washing:Operation with 6).
  10. Color:Add TMB Chromogen Solution A 50ul and then add TMB Chromogen Solution B 50ul to each well, mix gently,evade the light preservation for 15 min at 37℃
  11. Stop the Reaction:Add Stop Solution 50μl to each well, to stop the reaction(the blue color change to yellow color immediately).
  12. Assay:Set the OD of Blank well as zero , read absorbance at 450nm after adding Stop Solution within 15min.

The judgment of result must take the OD of Microplate reader as a standard, when use the dual-wavelength to assay, reference wavelength is 630nm.


Take the Standard density as the horizontal, the OD value for the vertical ,obtain the Standard Curve, then find out the corresponding density according to the sample OD value, and multiplied by the dilution multiple.
Or calculate the straight line regression equation of the standard curve with the standard density and the OD value ,with the sample OD value in the equation, calculate the sample density, multiplied by the dilution factor,the result is the sample actual density.

Note: This standard curve is provided for demonstration only. A standard curve should be generated for each set of samples assayed.




This assay is designed to eliminate interference by soluble receptors, binding proteins, and other factors present in biological samples. No significant cross-reactivity or interference between Chicken T COL and any of other cytokines.
Detection Range: 1.23 ng/ml- 100 ng/ml
Minimum Detection Limit: 1.23 ng/ml
Intra-assay Precision (Precision within an assay): CV (%) = SD/mean X 100 ≤ 9%
Three samples of known concentration (low, middle,and high level) were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV (%) = SD/mean X 100≤15%
Three samples of known concentration (low, middle,and high level) were tested in 20 separate assays to assess .
Correlation coefficient (R) of linear regression of the samples is more than 0.92


Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between Chicken T COL and all the analogues, therefore, cross reaction may still exist.


This plate can be used to layout and record standards and samples assayed.
