There are two good methods for assessing purity.
SDS-PAGE is polyacrylamide gel electrophoresis, performed in the presence of SDS (sodium dodecyl sulfate) which binds to proteins giving them a large net negative charge. Since the charges of all proteins are ...
The solution to this question provides two different methods for assessing the purity of a protein. This assessment is something that would typically be asked in a 1st-year biology lab. The two solutions are methods commonly employed by scientists involved in protein purification.
