Abstract
The invention is related to a method for purification of recombinant proteins using highly basic proteins from thermophilic bacteria as purification tags for use in a cation-exchange chromatography purification step. The basic proteins may be ribosomal proteins. The recombinant proteins are expressed in eukaryotic or prokaryotic host cells. The purification tag will typically have a pl above about 9 and comprise from about 15 to about 250 amino acid residues.
