Quantitative Detection Kit (ELISA) for Rat Oxidized Low Density Lipoprotein Antibody (OLAb) Instruction Manual [Kit Name] Quantitative Detection Kit for Rat Oxidized Low Density Lipoprotein Antibody (OLAb) [ELISA Kit] Quantitative Detection The content of oxidized low density lipoprotein antibody (OLAb) in rat serum, plasma and related fluid samples. [Detection principle] This kit adopts double antibody one-step sandwich enzyme-linked immunosorbent assay (ELISA). Add the standard, the test sample and the enzyme label working solution to the transparent enzyme label coated plate pre-coated with rat oxidized low density lipoprotein antibody (OLAb) antibody. After incubation for a sufficient time, wash to remove unbound components. . Add the developer A and B in turn, the developer (TMB) is converted into a blue product under the catalysis of horseradish peroxidase (HRP), and it becomes yellow under the action of acid. The color depth is larger than that in the sample. The concentration of mouse oxidized low-density lipoprotein antibody (OLAb) 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 rat oxidized low-density lipoprotein antibody (OLAb) was calculated. [Composition of the kit] 1 enzyme-labeled coating plate 12 wells × 8 strips 7 Developer A solution 6 mL 2 Standard: 480 U / L 0.6 mL 8 Developer B solution 6 mL 3 20-fold concentrated washing solution 25 mL 9 Stop solution 6 mL 4 standard Product Diluent 6mL 10 Instructions 1 copy 5 Sample Diluent 6mL 11 Sealing film 2 sheets 6 Enzyme Label Reagent 10mL 12 Sealed Bag 1 Remarks: The standard product diluent is diluted sequentially as follows: 480, 240, 120, 60, 30, 15 U / L [reagents and equipment not needed] 1, 37 ° C incubator 2, standard microplate reader 3, precision pipette and disposable pipette tip 4, distilled water 5, disposable test tube 6, Absorbent paper [Operation steps] 1. Preparation: Remove the reagent kit from the refrigerator, 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 the standard; add 10μL of the sample to be tested to the sample well, and then add 40μL of the sample diluent (that is, the sample is diluted 5 times); add 100μL of enzyme-labeled working solution to each well; no blank control well. 4. Incubation: Incubate in a 37 ° C water bath or thermostat for 60 minutes. 5. Wash the plate: discard the liquid, pat dry on the absorbent paper, fill each well with the washing liquid, let stand for 1min, shake off the washing liquid, pat dry on the absorbent paper, repeat the washing of the plate 5 times (you can also use the washing machine to press Instructions for washing the board). 6. Color development: add 50 μL of developer A solution to each well, then add 50 μL of developer B solution, and develop color at 37 ° C in the dark for 15 min. 7. 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). 8. 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. 9. 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] 1. The sample must not 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. 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 ℃, but repeated freezing and thawing should be avoided. 3. The sample should be fully centrifuged, without hemolysis and particles. [Notes] 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. If the color is too light, the substrate incubation time can be extended properly. 5. In order to avoid cross-contamination, the standard, sample and blank control should be replaced with a tip for each additional one; the common components such as enzyme working solution, sample diluent and substrate should be added by cantilever, and should not touch the microwell ; Do not reuse the sealing film. 6. The kits are used within the warranty period, and different batches of reagents should not be mixed. 7. Substrate B is sensitive to light and avoid prolonged exposure to light. [Summary of operating procedures] Prepare reagents, samples and standards, add the prepared samples, standards and enzyme standard working solution, wash the plate 5 times at 37 ° C for 60 minutes, add color developing solutions A and B, and develop at 37 ° C for 15 minutes Read the OD value within 15 minutes after adding the stop solution.
