This kit is for research use only.

Detection range: 96T

20 ng / L -480 ng / L

purpose of usage:

This kit is used to determine peroxisome proliferator-activated receptor γ in human serum, plasma and related liquid samples

(PPAR-γ) content.

Experimental principle

Human Peroxisome Proliferator Activated Receptor γ (PPAR-γ) Elisa Kit Instructions This kit uses the double antibody sandwich method to determine human peroxisome proliferator-activated receptor γ (PPAR-γ) in specimens

Level. A microplate was coated with purified human peroxisome proliferator-activated receptor γ (PPAR-γ) antibody to prepare a solid phase

Antibody, add PPAR-γ to the microwells coated with mAb in turn, and then combine with HRP-labeled PPAR-γ antibody to form

Antibody-antigen-enzyme-labeled antibody complex, after thorough washing, added substrate TMB for color development. TMB is catalyzed by HRP enzyme

Converted into blue, and into the final yellow under the action of acid. The color depth is positively correlated with PPAR-γ in the sample.

The absorbance (OD value) was measured with a microplate reader at a wavelength of 450 nm, and the concentration of human PPAR-γ in the sample was calculated by a standard curve.

Specimen requirements

1. Specimens are extracted as soon as possible after collection, and extraction is performed according to relevant literature, and experiments should be conducted as soon as possible after extraction. If not

Perform the test immediately. The specimen can be stored at -20 ℃, but repeated freezing and thawing should be avoided

2. The samples containing NaN3 cannot be detected because NaN3 inhibits horseradish peroxidase (HRP) activity.

Steps

1. Dilution of standard products: this kit provides one original standard product, the user can dilute in a small test tube according to the following chart

release.

480 ng / L No. 5 standard 150μl original standard added 150μl standard dilution

240 ng / L No. 4 standard 150μl No. 5 standard added 150μl standard dilution

120 ng / L No. 3 standard 150μl No. 4 standard added 150μl standard dilution

60 ng / L No. 2 standard 150μl No. 3 standard added 150μl standard dilution

30 ng / L No. 1 standard 150μl No. 2 standard added 150μl standard dilution

2. Add sample: set up blank wells (the blank control wells do not add samples and enzyme reagents, the rest of the operation is the same), standard well

Sample hole to be tested. Add 50μl of the standard on the enzyme-coated plate accurately, and add 40μl of sample diluent to the sample well.

Then add 10μl of the sample to be tested (the final dilution of the sample is 5 times). Add the sample to the bottom of the well of the microtiter plate

Do not touch the wall of the hole, shake gently to mix.

3. Incubation: seal the plate with the sealing film and incubate at 37 ° C for 30 minutes.

4. Mixing solution: Dilute 30 times concentrated washing liquid with distilled water 30 times and reserve

5. Washing: Carefully peel off the sealing film, discard the liquid, spin dry, fill each well with washing liquid, let stand for 30 seconds and then discard, so

Repeat 5 times and pat dry.

6. Add enzyme: add 50μl of enzyme label reagent to each well, except blank well.

7. Incubation: The operation is the same as 3.

8. Washing: The operation is the same as 5.

9. Color development: add 50μl of developer A to each well, and then add 50μl of developer B, mix gently, and develop color at 37 ℃ in the dark

15 minutes.

10. Termination: Add 50μl of stop solution to each well to terminate the reaction (at this time, the blue color turns to yellow).

11. Determination: Measure the absorbance (OD value) of each well in sequence with the blank air conditioner at zero and 450nm wavelength. Determination should be terminated

Within 15 minutes after the solution.

Summary of operating procedures:

Calculation

Taking the concentration of the standard as the abscissa and the OD value as the ordinate, draw a standard curve on the coordinate paper, according to the sample

The corresponding concentration of OD value is found by the standard curve; multiplied by the dilution factor; or the standard concentration and OD value are used to calculate the standard

The linear regression equation of the quasi-curve, the OD value of the sample is substituted into the equation, the sample concentration is calculated, and then multiplied by the dilution factor,

This is the actual concentration of the sample.

Precautions

1. The kit should be taken out of the refrigerated environment and equilibrated at room temperature for 15-30 minutes before it can be used.

After use, the slats should be stored in sealed bags.

2. Crystals may be precipitated in the concentrated washing liquid, which can be heated and dissolved in the water bath during dilution, and the results will not be affected during washing.

3. The sample adder should be used in each step of sample addition, and its accuracy should be regularly checked to avoid test errors. One sample loading time is best

Control within 5 minutes, if the number of specimens is large, it is recommended to use a volley gun to add samples.

4. Please make the standard curve at the same time of each measurement, it is better to make the complex hole. If the content of the test substance in the specimen is too high (sample OD value

Is greater than the OD value of the first well of the standard product), please dilute it with a certain multiple (n times) of the sample diluent before measuring.

When calculating, please multiply the total dilution factor (× n × 5).

5. The sealing film is limited to one-time use to avoid cross contamination.

6. Please keep the substrate away from light.

7. Strictly follow the instructions, and the test results must be determined based on the reading of the microplate reader.

8. All samples, washing liquid and various wastes should be treated as infectious agents.

9. The components of different batches of this reagent shall not be mixed.

10. If there is any difference with the English manual, the English manual shall prevail.
