And so that's exactly what we normally have to do. So to solve the problem, we can cleave the protein into many smaller fragments and then use the Edmund degradation process on each individual process. So let's suppose we have the following polypeptide. So we take that polypeptide, we mix it with some type of molecule that cleaves those peptide bonds. And so for example, if you use a specific type of biological enzyme, for example, let's say we cleave it in this position and in this position. And so we produce fragments A, B and C. Now we can separate the fragments, for example, based on size by using SDS polyacrylamide, gel electrophoresis.
