In order to measure the concentration of BNPin the sample, this BNPELISA Kit includes a set of calibration standards. The calibration standards are assayed at the same time as the samples and allow the operator to produce a standard curve of Optical Density versus BNPconcentration. The concentration of BNPin the samples is then determined by comparing the O.D. of the samples to the standard curve.Samplecollection and storagesSerum- Use a serum separator tube and allow samples to clot for 30 minutes before centrifugation for 10 minutes at approximately 3000×g. Remove serum and assay immediately or aliquot and store samples at -20℃ or -80℃.Avoid repeated freeze-thaw cyclesPlasma- Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples for 30minutes at 3000×g at 2-8℃ within 30 minutes of collection. Store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.Cell culture supernates and other biological fluids-Remove particulates by centrifugation and assay immediately or aliquot and store samples at -20℃or -80℃. Avoid repeated freeze-thaw cycles.Note: The samples shoule be centrifugated dequately and no hemolysis or granule was allowed.Materials required but not supplied1. Standard microplate reader(450nm)2.

Aspirate each well and wash, repeating the process fourtimes for a total of five washes.Wash by filling each well with Wash Solution(400μl) using a squirt bottle, manifolddispenseror autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Solutionby aspirating ordecanting. Invert the plate and blot it against clean paper towels.6. Add chromogen solution A 50μl and chromogen solution B 50μl to each well.Gently mix and incubate for 15 minutes at 37°C. Protect from light.7. Add 50μl Stop Solution to each well. The color in the wells should change from blue toyellow. If the color in the wells is green or the color change does not appear uniform,gently tap the plate to ensure thorough mixing.8. ReadtheOpticalDensity(O.D.)at450nmusinga microtiterplatereaderwithin15minutes.Calculation of results1.This standard curve is used to determine the amount in an unknown sample. The standard curve is generated by plotting the average O.D. (450 nm) obtained for each of the six standard concentrations on the vertical (Y) axis versus the corresponding concentration on the horizontal (X) axis. 2.First, calculate the mean O.D. value for each standard and sample. All O.D. values, are subtracted by the mean value of the zero standard before result interpretation. Construct the standard curve using graph paper or statistical software. 3.To determine the amount in each sample, first locate the O.D. value on the Y-axis and extend a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the X-axis and read the corresponding concentration. 4.Any variation in operator, pipetting and washing technique, incubation time or temperature, and kit age can cause variation in result. Each user should obtain their own standard curve.5.The sensitivity by this assay is1.0 pg/ml6.Standard curveStorage: 2-8℃.validity: six months.FOR RESEARCH USE ONLY; NOT FOR THERAPEUTIC OR DIAGNOSTIC APPLICATIONS!PLEASE READ THROUGH ENTIRE PROCEDURE BEFORE BEGINNING! 查看详细∨
