Quantitative detection of serum, plasma and related fluids.

[Chicken secreted immunoglobulin A (SIgA) ELISA kit detection principle]

This kit uses double-antibody two-step sandwich enzyme-linked immunosorbent assay (ELISA). Add the standard and the test sample to the pre-coated chicken secreted immunoglobulin A (SIgA) monoclonal antibody transparent enzyme label coating plate. After incubation for a sufficient time, wash to remove unbound components, and then add the enzyme label After incubating the working solution for a sufficient period of time, wash to remove unbound components. Substrates A and B are added in sequence, and the substrate (TMB) is converted into a blue product catalyzed by horseradish peroxidase (HRP), which turns yellow under the action of an acid. The concentration of globulin A (SIgA) was positively correlated. The OD value was measured at a wavelength of 450 nm. Based on the OD value of the standard and the sample, the content of chicken secretory immunoglobulin A (SIgA) in the sample was calculated.

6. Absorbent paper

[Operation steps of chicken secretory immunoglobulin A (SIgA) ELISA kit]

1. Preparation: Remove the reagent kit from the refrigerator and re-equilibrate at room temperature for 30 minutes.

2. Mixing solution: dilute the 20-fold concentrated washing solution with distilled water to the original one.

3. Add standard products and samples to be tested: take a sufficient number of enzyme-coated plates and fix them to the frame. Set up standard wells, sample wells to be tested and blank control wells, record the positions of each well in the standard wells. Add 50μL of standard product; first add 10μL of sample to be tested, and then add 40μL of sample diluent (that is, the sample is diluted 5 times); blank control well is not added.

4. Incubation: Incubate in a 37 ° C water bath or thermostat for 30 minutes.

5. Wash the plate: discard the liquid, pat dry on the absorbent paper, fill each hole with the washing solution, let stand for 1min, shake off the washing solution, pat dry on the absorbent paper, repeat the washing 4 times (you can also use the washing machine to press Instructions for washing the board).

6. Add enzyme-labeled working solution: add 50μL of enzyme-labeled working solution to each well, without adding blank control wells.

7. Incubation: Incubate in a 37 ° C water bath or thermostat for 30 minutes.

8. Wash the plate: discard the liquid, pat dry on the absorbent paper, fill each hole with washing liquid, let stand for 1min, shake off the washing liquid, pat dry on the absorbent paper, repeat the plate washing 4 times (you can also use the washing machine to press Instructions for washing the board).

9. Color development: add 50μL of developer A solution to each well, and then add 50μL of developer B solution, mix for 30s with a plate mixer (or gently shake for 30s by hand), and avoid color development at 37 ℃ for 15min .

10. Termination: Remove the enzyme labeling plate and add 50μL of stop solution to each well to stop the reaction (the color changes from blue to yellow)

11. Determination: Zero the blank holes, and within 15 minutes after termination, measure the absorbance (OD value) of each well with a wavelength of 450 nm.

12. Calculation: According to the concentration of the standard product and the corresponding OD value, calculate the linear regression equation of the standard curve, and then calculate the corresponding sample concentration on the regression equation according to the OD value of the sample. You can also use various application software to Calculation. The final concentration is the actual measured concentration times the dilution factor.

[Sample Requirements for Chicken Secretory Immunoglobulin A (SIgA) ELISA Kit]

1. The sample cannot contain sodium azide (NaN3) because sodium azide (NaN3) is an inhibitor of horseradish peroxidase (HRP).

2. The specimen should be extracted as soon as possible after collection. The extraction should be carried out according to relevant literature. If the test cannot be performed immediately, the specimen can be stored at -20 ℃, but repeated freezing and thawing should be avoided.

3. The sample should be fully centrifuged, without hemolysis and particles.

[Precautions for Chicken Secretory Immunoglobulin A (SIgA) ELISA Kit]

1. The experiment is carried out in strict accordance with the instructions, and the result of the experiment must be determined by the reading of the microplate reader.

2. If the enzyme-labeled coated board is not used up after opening, it should be put into a sealed bag and added with desiccant immediately.

3. It is recommended that all standards, samples and blank controls be tested in duplicate, and the average value is taken to reduce the experimental error.

4. Keep in mind that the sample has been diluted 5 times. The calculation result is multiplied by 5 to obtain the actual concentration of the sample.

5. The quantitative range of this kit is 6.25-200ng / L. If it exceeds this range, it is calculated from the extension of the standard curve. It is not used for accurate quantitative results. ), Multiplied by the total dilution factor is the final concentration of the sample.

6. If the color is too light, the substrate incubation time can be extended properly.

7. In order to avoid cross-contamination, the tips, samples and blank controls should be replaced with a new one for each addition; the common components such as enzyme working solution, sample diluent and substrate should be cantilevered, and they should not touch the microwells. ; Do not reuse the sealing film.

8. The kits are used within the warranty period, and different batches of reagents should not be mixed.

9. Substrate B is sensitive to light and avoid prolonged exposure to light.
