First step in protein purification
WebFigure 1: Flow chart of protein working step. To obtain desired protein from the solution is the first step of successfully protein purification, after which soluble protein can be obtained .This flow chat gives broad outline of the methods used for successful soluble and insoluble recombinant and non-recombinant proteins. WebMore commonly, however, AC is used as the first capture step, followed by one or more polishing steps to remove remaining impurities. For example, protein A or protein G ligands coupled to an agarose base matrix are used for routine purification of antibodies. Today, most laboratory-scale purifications are performed with affinity-tagged proteins.
