Affinity chromatography fraction can be analyzed by two ways

Absorption or UV visible spectrophotometry which analyzes the concentration of protein in the fraction by using Beer lamberts law.

Polyacrylamide gel electrophoresis to fractionize the protein sample on the basis of their molecular weight.
