Abstract

Substantially pure histidine-linked protein-polymer conjugates and processes for their preparation are disclosed. The processes include contacting a protein with an activated polymer under conditions sufficient to facilitate covalent attachment of at least a portion of the polymer strands on histidine residues of the protein and thereafter substantially separating the histidine-linked conjugates from the remaining reactants.
