There are four basic steps of protein purification: 1) cell lysis, 2) protein binding to a matrix, 3) washing and 4) elution. Cell lysis can be accomplished a number of ways, including nonenzymatic methods (e.g., sonication or French press) or use of hydrolytic enzymes such as lysozyme or a detergent reagent such as FastBreak™ Cell Lysis Reagent.
