t-Boc-N-amido-dPEG₃₆-acid is a monodisperse PEG product that is useful for peptide synthesis. The 112-atoms-long dPEG spacer allows the introduction of a long, hydrophilic spacer onto either end of a peptide chain or on an amino acid side chain. The flexible dPEG spacer conjugates to peptides using conventional peptide synthesis chemistry. The Boc protecting group removes easily with acids such as trifluoroacetic acid (TFA), HF, and trifluoromethane sulfonic acid (TFMSA). Peptide PEGylation imparts water solubility to hydrophobic peptide chains, expands the PEG-peptide conjugates′ hydrodynamic volumes (thus decreasing renal clearance), and protects PEGylated peptides from proteolysis. The combination of decreased renal clearance and protection from proteolysis contributes to longer in vivo circulation times for PEGylated (as compared to non-PEGylated) peptides. Additionally, PEGylation diminishes a peptide′s antigenicity. This product is part of the t-Boc-N-amido-dPEG_n-acid (n=4, 8, 12, 24, 36) product series.
