You need to separate the following three proteins, Protein A (MW 76 600 Da; pI 4.5); Protein B (MW 70 000 Da and pI 8.2) and Protein C (MW 42 000; pI 8.6). Describe what column/s you would use, the pH of the buffer/s you would use, which proteins are retained on the column and how you would elute the bound protein/s.                                                     How would you monitor where the protein peaks elute and whether the protein in each peak is pure of not?
