Chlamydia IgG (Chlamydia IgG) enzyme-linked immunoassay (ELISA) kit instructions for use This reagent is for research purposes only: This kit is used to determine the content of Chlamydia IgG (Chlamydia IgG) in parrot serum, plasma and related liquid samples. Experimental principle: This kit uses the double antigen sandwich method to determine the level of Chlamydia IgG (Chlamydia IgG) in the specimen. The microplate is coated with purified antigen to make a solid-phase antigen. Chlamydia IgG (Chlamydia IgG) is added to the microwells coated with mAb in turn, and then combined with HRP-labeled antigen to form an antigen-antibody-enzyme-labeled antigen complex After thorough washing, add substrate TMB to develop color. TMB is converted into blue under the catalysis of HRP enzyme, and into the final yellow under the action of acid. The color depth is positively correlated with Chlamydia IgG in the sample. The absorbance (OD value) was measured with a microplate reader at a wavelength of 450 nm, and the concentration of Chlamydia IgG (Chlamydia IgG) in the sample was calculated by a standard curve.

Processing and requirements: 1. Serum: room temperature blood is naturally coagulated for 10-20 minutes, centrifuged for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully and centrifuge again if a precipitate appears during storage. 2. Plasma: EDTA or sodium citrate should be selected as the anticoagulant according to the requirements of the specimen, mixed for 10-20 minutes, and centrifuged for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. If a precipitate forms during storage, it should be centrifuged again. 3. Urine: collected in a sterile tube and centrifuged for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. If a precipitate forms during storage, centrifuge again. Pleural and ascites, cerebrospinal fluid reference implementation. 4. Cell culture supernatant: When detecting secreted components, collect with a sterile tube. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. When detecting the components inside the cells, dilute the cell suspension with PBS (PH7.2-7.4), and the cell concentration will reach about 1 million / ml. Through repeated freezing and thawing, the cells are destroyed and the intracellular components are released. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. If a precipitate forms during storage, it should be centrifuged again. 5. Organize the specimen: after cutting the specimen, weigh it. Add a certain amount of PBS, PH7.4. Quickly freeze and save with liquid nitrogen for later use. After the specimen melts, it still maintains a temperature of 2-8 Â° C. Add a certain amount of PBS (PH7.4) and homogenize the specimen with a manual or homogenizer. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. After aliquoting, a portion is to be tested, and the rest is frozen for future use. 6. The specimen should be extracted as soon as possible after collection. The extraction should be carried out according to relevant literature. The experiment should be carried out as soon as possible after extraction. If the test cannot be performed immediately, the specimen can be stored at -20 Â° C, but repeated freezing and thawing should be avoided. 7. Samples containing NaN3 cannot be detected because NaN3 inhibits the activity of horseradish peroxidase (HRP). Procedure 1. Dilution and loading of standard products: set 10 standard wells on the enzyme-coated plate, add 100 Î¼l of standard products in the first and second wells, and then add in the first and second wells. 50Î¼l of standard diluent, mix well; then take 100Î¼l from the first well and the second well respectively to the third and fourth wells, then add 50Î¼l of standard diluent to the third and fourth wells respectively, mix Evenly; then take 50Î¼l each in the third and fourth wells and discard, then add 50Î¼l each to the fifth and sixth wells, and then add 50ul of standard dilution solution to the fifth and sixth wells respectively, mix After mixing, take 50Î¼l from the fifth and sixth wells and add them to the seventh and eighth wells respectively. Then add 50Î¼l of the standard dilution solution to the seventh and eighth wells respectively. Take 50Î¼l from the eighth well to the ninth and tenth wells, and then add 50Î¼l of the standard dilution solution to the ninth and tenth wells respectively. After mixing, take 50Î¼l from the ninth and tenth wells and discard. (After dilution, the sample volume of each well is 50 Î¼l, and the concentrations are 60 ng / L, 40 ng / L, 20 ng / L, 10 ng / L, and 5 ng / L respectively). 2. Add samples: set up blank wells (the blank control wells do not add samples and enzyme reagents, the rest of the steps are the same) and the sample wells to be tested. Add 40Î¼l of sample diluent to the test sample well of the enzyme-coated plate, and then add 10Î¼l of the sample to be tested (the final dilution of the sample is 5 times). Add the sample and add the sample to the bottom of the well of the microplate, try not to touch the wall of the well, shake gently to mix. 3. Incubation: Seal the plate with a sealing plate and incubate at 37 Â° C for 30 minutes. 4. Mixing solution: Dilute 30 times (20 times of 48T) concentrated washing liquid with distilled water 30 times (20 times of 48T) and then use. 5. Washing: Carefully peel off the sealing film, discard the liquid, spin dry, fill each well with the washing liquid, let it stand for 30 seconds and then discard, repeat this 5 times, pat dry. 6. Add enzyme: add 50Î¼l 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 50Î¼l of developer A to each well, then add 50Î¼l of developer B, mix gently, and develop color at 37 Â° C in the dark 15 minutes. 10. Termination: Add 50 Î¼l of stop solution to each well to stop the reaction (the blue color turns to yellow at this time). 11. Determination: Measure the absorbance (OD value) of each well in sequence with the blank air conditioner at zero and 450 nm wavelength. The measurement should be carried out within 15 minutes after adding the stop solution. Note: 1. The kit should be equilibrated at room temperature for 15-30 minutes before being taken out of the refrigerated environment. If the enzyme label coated plate is unopened, the strip should be stored in a sealed bag. 2. Crystals may be precipitated in the concentrated washing liquid, which can be heated and dissolved in a water bath during dilution, and the results will not be affected during washing. 3. The sampler should be used at each step of sample addition, and the accuracy should be regularly checked to avoid test errors. It is best to control the sampling time within 5 minutes. If there are many specimens, it is recommended to use a volley gun to add samples. 4. Please make a standard curve at the same time of each measurement, it is best to make a double hole. If the content of the test substance in the specimen is too high (the OD value of the sample is greater than the OD value of the first well of the standard well), please first dilute it with a certain multiple (n times) of the sample diluent and then determine it. When calculating, please multiply the total dilution Multiple (Ã— n Ã— 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 liquids 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. Calculation: take the concentration of the standard as the abscissa and the OD as the ordinate, draw a standard curve on the coordinate paper, and find the corresponding concentration from the standard curve according to the OD value of the sample; multiply by the dilution factor; or use the standard The linear regression equation of the standard curve is calculated by the concentration and OD value of the sample, the OD value of the sample is substituted into the equation, the sample concentration is calculated, and then multiplied by the dilution factor, which is the actual concentration of the sample.
