The correlation coefficient of an acceptable calibration is 0.9 or better.
WebPerform standard curve analysis to ELISA data. With Labii's ELISA Data Analysis widget, you can document and analyze the data in a few clicks, and the result is ready in a few seconds. Labii's ELISA Data Analysis … WebA standard curve, also known as a calibration curve, is a type of graph used as a quantitative research technique. Multiple samples with known properties are measured and graphed, which then allows the same properties to be determined for unknown samples by interpolation on the graph.
In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration. A calibration curve is one approach to the problem of instrument calibration; other standard approaches may mix the standard into the unknow… WebHow is a standard curve constructed? In short, standard curves are graphs constructed using data from known samples. To use a curve you need known amounts …
WebStandard curves are always plotted as the Standards on the x-axis and absorbances on the y-axis, however to make solving the polynomial equations easier, plot absorbances on the x-axis and protein concentration on the y-axis. Now simply plug the absorbances (x) into the polynomial equation and solve for y (Protein concentration).
