Protein Purification
3 Activities
Which of these options would not be a possible step in a protein purification protocol?
Once you break open the bacterial host cells, you run an SDS-PAGE gel to verify the presence of your protein by separating all proteins based on their size and charge.
You have run a Nickel column on a His-tagged protein and you isolate your protein (34 kDa) and a contaminating protein (70 kDa). You then run gel filtration to separate these protein based on size.
If you run an gel filtration column you are separating proteins based on their size.
