How to do standard curve
WebThe protein concentration of an unknown sample is calculated from the standard curve that is generated form the known protein standards. If the protein concentration of the unknown samples lie ... WebThe value on the y axis just denotes the value of the probability density function evaluated at different values of x. In the center of the top of the bell curve, a line drops straight down which is the y axis. The bell curve (Gaussian) is a standard bell curve, meaning it is used to measure other things.

The sample data may be partly covered by a floating note explaining how to fit the data (for people who are not reading this help page). You can move the floating note out of the way, or minimize it. The first seven rows contain the standard curve, in duplicate. Webused. A standard curve was developed using a series of Bovine Serum Albumin (BSA) standards in the 100 g/ml to 1,500 g/ml range. The absorbance of each sample was measured at 595 nm and plotted versus [BSA]. The resulting line was fit by the linear least squared method. Samples from the cell free and stage 1 extracts were subjected to
