What is a standard curve and how is it constructed?

WebIn short, standard curves are graphs constructed using data from known samples. To use a curve you need known amounts of the substance (e.g. toxin) you want to test (in the unknown sample). You must test the standards and unknown samples at the same time. You then need to draw a graphic. What is the purpose of the BSA? WebProtein Standard Curve Version 6-18-12 • Standard curves are used in many assays in biotechnology. • The idea involves making a series of standard solutions that are then assayed for their value.
