We simply use Excel which has a linear regression function called
TREND. Type in standards, readings and unknowns, then use TREND to
calculate the protein concentration in each unknown. Spend a short time
playing with the help file and create a nice spreadsheet. Then just use
it over and over. It even draws the curve with the regression line and
generates a report if you wish.
