PhyTip columns with CaptureSelect FcXL affinity matrix can be used for purification of recombinant human IgG, Fc fusion proteins and plasma derived IgG by binding to the CH3 domain of all human IgG subclasses (I, II, III and IV).

The affinity ligands of CaptureSelect™ medias from ThermoFisher are based on a recombinant antibody fragment of only 14 kDa in size that can be adapted for highly selective binding to certain parts or antibodies and antibody fragments.
