Anwendung

Polyethylene glycol 2000 is used in the construction of biomaterials such as biopolymers, micelles and nanostructures.

Biochem./physiol. Wirkung

O-Methyl-O′-succinylpolyethylene glycol 2′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.

Stepwise synthetic assembly of polypeptide chains reversibly linked to polyethylene glycol represents a hybrid between traditional solution and solid-phase chemistries and combines the inherent advantages of both approaches. The technical simplicity and scalability of the liquid-phase peptide synthesis method renders

We previously reported on a stearylated INF7 peptide (str-INF7), which enhances the endosomal escape of an octaarginine (R8)-modified liposomal particle encapsulating plasmid DNA (pDNA) in a fusion-independent manner. This study examined whether this peptide derivative enhanced the endosomal escape and

Recent studies from this laboratory showed that tolerogenic peptide conjugates are very effective reagents for obtaining epitope-specific immunosuppression of antibody responses to immunopathogenic sites on multideterminant complex protein antigens. This paper describes the procedure for synthesis of well-defined conjugates of
