Human NCOA2 ELISA Kit Instruction Manual
This reagent is for research use only: This kit is used to determine the content of human NCOA2 in human serum, plasma and related liquid samples. Experimental principle : This kit uses the double antibody sandwich method to determine the level of human NCOA2 in the specimen. The microplate was coated with purified human NCOA2 antibody to prepare a solid phase antibody, and NCOA2 was sequentially added to the microcapsule of the coated monoclonal antibody, and then bound to the HRP-labeled NCOA2 antibody to form an antibody-antigen-enzyme-labeled antibody complex. After thorough washing, the substrate TMB was added to develop color. TMB is converted to blue under the catalysis of HRP enzyme and converted to the final yellow color by the action of an acid. The color depth is positively correlated with NCOA2 in the sample. The absorbance (OD value) was measured by a microplate reader at a wavelength of 450 nm, and the content of human NCOA2 in the sample was calculated by a standard curve.

Serum: The blood is naturally coagulated for 10-20 minutes at room temperature and centrifuged for about 20 minutes (2000-3000 rpm). The supernatant is carefully collected, and if precipitation occurs during storage, it should be centrifuged again. 2. Plasma: EDTA or sodium citrate should be selected as an anticoagulant according to the requirements of the specimen. After mixing for 10-20 minutes, centrifuge for about 20 minutes (2000-3000 rpm). The supernatant is carefully collected, and if a precipitate forms during storage, it should be centrifuged again. 3. Urine: Collect with a sterile tube and centrifuge for about 20 minutes (2000-3000 rpm). The supernatant is carefully collected, and if a precipitate forms during storage, it should be centrifuged again. The chest and ascites and cerebrospinal fluid are referred to. 4. Cell culture supernatant: When detecting secreted components, collect them in a sterile tube. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. When the components in the cells were detected, the cell suspension was diluted with PBS (pH 7.2-7.4), and the cell concentration reached about 1 million/ml. By 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. Tissue specimen: After cutting the specimen, weigh the weight. Add a certain amount of PBS, pH 7.4. It was quickly frozen and stored in liquid nitrogen for use. The specimen still maintains a temperature of 2-8 ° C after melting. A certain amount of PBS (pH 7.4) was added, and the specimen was homogenized by hand or homogenizer. Centrifuge for about 20 minutes (2000-3000 rpm). Collect the supernatant carefully. One part of the package is to be tested, and the rest is frozen for use. 6. The specimens should be extracted as soon as possible after collection, and the extraction should be carried out according to the 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 °C, but repeated freezing and thawing should be avoided. 7. Samples containing NaN3 cannot be detected because NaN3 inhibits horseradish peroxidase (HRP) activity. Steps Precautions: 10. In the case of an English manual, the English manual shall prevail. Calculation : Taking 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 concentration of the standard Calculate the linear regression equation of the standard curve with the OD value, substitute the OD value of the sample into the equation, calculate the sample concentration, and multiply by the dilution factor, which is the actual concentration of the sample. Kit performance: 1. The linear regression coefficient of the sample and the expected concentration correlation coefficient R value is 0.990 or more. 2. Within and within the batch should be less than 9% and 11% respectively examination range: 35pg/mL -1200pg/mL Storage conditions and expiration date: 1. Kit storage: 2-8 ° C. 2. Validity: 6 months
