Pearl™ IgG Purification Resin allows for the one-step purifiication of the immunoglobulin G (IgG) antibodies from serum.The resin binds the high abundant, non-IgG proteins (i.e albumin) and allows the IgG molecules to pass through in a physiological buffer.The purified IgG molecules can be stored or used in further downstream applications without further clean-up, such as ammonium sulfate precipitation.
Pearl™ IgG Purification Resin can purify IgG in <15 minutes, which is more rapid than the commonly used Protein A and Protein G resins. The performance of the Pearl™ IgG Purification Resin is comparable or better than the ProteinA and Protein G resins.
