You are trying to purify Protein 1 from a mix of 4 different proteins without denaturing the protein. Protein 1 has a molecular weight of 3,000 Daltons and is very rich in lysine (Lys: K) Protein 2 has a molecular weight of 30,000 Daltons and is very rich in aspartic acid (Asp: D) Protein 3 has a molecular weight of 300,000 Daltons and is very rich in arginine (Arg: R) Protein 4 has a molecular weight of 30,000 Daltons and is very rich in histidine (His: H) What type of matrix/technique would make the most sense to use?
