In order to measure the concentration of MBP;MBLin the sample, this MBP;MBLELISA 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 MBP;MBLconcentration. The concentration of MBP;MBLin 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℃.

ReadtheOpticalDensity(O.D.)at450nmusinga microtiterplatereaderwithin15minutes.Calculation of resultsThis 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. 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. 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. 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.The sensitivity by this assay is10 ng/mL.Standard curveStorage： 2-8℃.validity： six months.FOR RESEARCH USE ONLY; NOT FOR THERAPEUTIC OR DIAGNOSTIC APPLICATIONS!PLEASE READ THROUGH ENTIRE PROCEDURE BEFORE BEGINNING! 关注本网官方微信 随时阅读专业资讯
