Abstract
The present invention provides methods for separating proteins from a protein mixture. In one aspect, a method for separating a high concentration protein mixture into a bound protein fraction and a flow-through protein fraction can include delivering a protein mixture through an ion exchange column at a fixed pH and a fixed salt concentration. The fixed pH and the fixed salt concentration have been preselected to cause separation of the protein mixture into a bound protein fraction and a flow-through protein fraction. In this case, the bound protein fraction binds to the ion exchange column and the flow-though protein fraction flows though the ion exchange column. The method can further include receiving the flow-through protein fraction from the ion exchange column separate from the bound protein fraction, wherein either the bound protein fraction or the flow-through fraction contains a protein of interest.
