Mouse Valine ELISA Kit instruction Intended useThis Valine ELISA kit is intended LaboMouseory for Research use only and is not for use in diagnostic or therapeutic procedures.The Stop Solution changes the color from blue to yellow and the intensity of the color is measured at 450 nm using a spectrophotometer. In order to measure the concentMouseion of Valine in the sample, this Valine ELISA Kit includes a set of calibMouseion standards. The calibMouseion standards are assayed at the same time as the samples and allow the opeMouseor to produce a standard curve of Optical Density versus Valine concentMouseion. The concentMouseion of Valine in the samples is then determined by comparing the O.D. of the samples to the standard curve.Sample collection and storagesSerum - Use a serum sepaMouseor 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 30 minutes 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℃.

Read the Optical Density (O.D.) at 450 nm using a microtiter plate reader within 15 minutes.Calculation of results1. This standard curve is used to determine the amount in an unknown sample. The standard curve is geneMouseed by plotting the average O.D. (450 nm) obtained for each of the six standard concentMouseions on the vertical (Y) axis versus the corresponding concentMouseion 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 concentMouseion. 4. Any variation in opeMouseor, pipetting and washing technique, incubation time or tempeMouseure, and kit age can cause variation in result. Each user should obtain their own standard curve.5. The sensitivity by this assay is 1.0 μmol/L6. Standard curve Storage: 2-8℃.validity: six months. FOR RESEARCH USE ONLY; NOT FOR THERAPEUTIC OR DIAGNOSTIC APPLICATIONS!
