Abstract: Water soluble polymers having formula I: Y-(L1)n1-(C(O))n2—(R1)n3—R2 are claimed. The polymers may contain multiple water soluble, immunogenicity reducing moieties and multiple active moieties. The polymers may be linked to a protein, or a peptide having up to twelve amino acids.

Abstract: A delivery system for delivering oligonucleotides includes a conjugate includes a complexing agent including an oligonucleotide, a peptide nucleic acid or chimera thereof and a polymer covalently attached to the complexing agent. The complexing agent of the conjugate is adapted to complex a biologically active agent thereto after formation of the conjugate.

Abstract: This invention pertains to methods for producing homogeneous recombinant proteins that contain polymer initiators at defined sites. The unnatural amino acid, 4-(2?-bromoisobutyramido)phenylalanine of formula 1, was designed and synthesized as a molecule comprising a functional group further comprising an initiator for an atom-transfer radical polymerization (‘ATRP”) that additionally would provide a stable linkage between the protein and growing polymer. We evolved a Methanococcus jannaschii (Mj) tyrosyl-tRNA synthetase/tRNACUA pair to genetically encode this unnatural amino acid in response to an amber codon. To demonstrate the utility of this functional amino acid, we produced Green Fluorescent Protein with the unnatural amino acid initiator of formula 1 site-specifically incorporated on its surface (GFP-1).
