Experimental principle
The kit uses a double antibody one-step sandwich method for enzyme-linked immunosorbent assay (ELISA). 小鼠多囊肾蛋白1 Polycystin 1 )捕获抗体的包被微孔中,依次加入标本、标准品、HRP标记的检测抗体,经过温育并彻底洗涤。 Into the microwells coated with mouse polycystin 1 capture antibody, add specimens, standards, and HRP-labeled detection antibodies in order, incubate and wash thoroughly. The color is developed with the substrate TMB, and TMB is converted to blue by peroxidase catalysis, and is converted to the final yellow by the action of acid. 小鼠多囊肾蛋白1 Polycystin 1 )呈 正相关。 The shade of color is positively correlated with mouse polycystin 1 in the sample . Measure the absorbance (OD value) at 450nm with a microplate reader to calculate the sample concentration.
Sample processing and requirements
血清 :全血标本请于室温放置2小时或4℃过夜后于1000g离心20分钟,取上清即可检测,或将标本放于-20℃或-80℃保存,但应避免反复冻融。 1. Serum : Whole blood samples should be left at room temperature for 2 hours or 4 C overnight. Centrifuge at 1000g for 20 minutes, and then take the supernatant to test. Or store the samples at -20 C or -80 C, but avoid repeated freezing. melt.
血浆 :可用EDTA或肝素作为抗凝剂,标本采集后30分钟内于2 - 8C 1000g离心 20 分钟,或将标本放于-20℃或-80℃保存,但应避免反复冻融。 2. Plasma : EDTA or heparin can be used as an anticoagulant. Centrifuge at 1000 g at 2-8 C for 20 minutes within 30 minutes after collection , or store the sample at -20 C or -80 C, but avoid repeated freeze-thaw cycles. .
组织匀浆 :用预冷的PBS (0.01M, pH=7.4)冲洗组织,去除残留血液(匀浆中裂解的红细胞会影响测量结果),称重后将组织剪碎。 3. Tissue homogenate : Rinse the tissue with pre-chilled PBS (0.01M, pH = 7.4) to remove residual blood (the lysed red blood cells in the homogenate will affect the measurement result), and cut the tissue after weighing. The cut tissue and the corresponding volume of PBS (generally based on a weight to volume ratio of 1: 9, such as 1g of tissue sample corresponds to 9mL of PBS, the specific volume can be adjusted according to the needs of the experiment, and make a record. It is recommended to add Protease inhibitors) were added to a glass homogenizer and ground thoroughly on ice. To further lyse the tissue cells, the homogenate can be sonicated or repeatedly freeze-thaw. Finally, the homogenate was centrifuged at 5000 g for 5-10 minutes, and the supernatant was taken for detection.
. 细胞培养物上清或其它生物标本 :1000g离心20分钟,取上清即可检测,或将标本放于-20℃或-80℃保存,但应避免反复冻融。 4. Cell culture supernatant or other biological specimens : Centrifuge at 1000g for 20 minutes, and take the supernatant for detection, or store the specimens at -20 C or -80 C, but avoid repeated freeze-thaw cycles.
Note: The hemolysis of the specimen will affect the final test results, so this test should not be performed on hemolyzed specimens.

Specimen processing
1. The company is only responsible for the kit itself, not for sample consumption caused by using the kit. Users are requested to fully consider the possible use of the sample before use, and reserve sufficient samples.
2. The content of the specimen should be predicted before the experiment. If the concentration of the specimen is too high, the specimen should be diluted so that the diluted specimen conforms to the detection range of the kit and then multiplied by the corresponding dilution factor during calculation. Specimens were diluted with 0.01mol / L PBS (PH = 7.0-7.2).
3. If the tested samples are not included in the samples listed in the instruction manual, it is recommended to conduct pre-experiments to verify their effectiveness, and pay attention to retaining the samples.
4. Tissue homogenates or cell extracts prepared using chemical lysates may cause deviations in ELISA results due to the introduction of certain chemicals.
5. If the sample is a cell culture supernatant, it may not be detected because there are many interference factors in this type of sample, such as: cell status, cell number, and sampling time.
6. Certain natural or recombinant proteins, including prokaryotic and eukaryotic recombinant proteins, may not be detected because they do not match the detection and capture antibodies used in this product.
7. It is recommended to use fresh samples. Excessive storage time may result in protein degradation or denaturation, which may lead to deviations in experimental results.
