How to do standard curve

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… WebWhen using the standard curve method, the quantity of each experimental sample is first determined using a standard curve, and is then expressed relative to a calibrator sample. In order to use this quantification method, prepare five (5) 2-fold, 5-fold, or 10-fold serial dilutions of cDNA template known to express the gene of interest in high abundance.
