Biochem/physiol Actions
O-Methyl-O′-succinylpolyethylene glycol 5′000 is a modified monomethoxypolyethylene glycol (mPEG) wherein the hydroxyl groups are succinylated by succinic anhydride. This succinylated mPEG can then be used to synthesize tolerogenic mPEG conjugates of peptides. Tolerogenic peptide conjugates are very effective reagents for obtaining epitope-specific immunosuppression of antibody responses to immunopathogenic sites on multideterminant complex protein antigens.

A co-polymer of O-methyl polyethylene(glycol)-O'-succinate (MPEGs, m.w. 5100) and poly-l-lysine (PL, median m.w. 32700, degree of polymerization 256) has been synthesized by covalent grafting. The resultant MPEGs-PL (30% modification degree of epsilon-amino groups) had a hydrodynamic diameter corresponding to a
Enhanced stability of PEG-block-poly(N-hexyl stearate l-aspartamide) micelles in the presence of serum proteins.
Methods in molecular biology (Clifton, N.J.), 570, 309-316 (2009-08-04)
Combinatorial synthesis of peptides on solid supports (1), either as spots on cellulose membranes (2) or with split-pool-libraries on polymer beads (3), substantially forwarded research in the field of peptide-protein interactions. Admittedly, these concepts have specific limitations, on one hand
