PEG derivatives are known not onlyto increase drug circulation time, solubility and stabilitybut alsoreduce immunogenicity and toxicitywhen attached to a drug.These potential advantages allow manyapplications such as Pegylated-protein/peptide drugs,-hydrogels, -liposomes for pharmaceutical uses and Pegylated-hemoglobin as oxygen/CO2carrier.

We supply various polyethyleneglycol derivatives of high qualityavailable at commercial scale and cGMP grade.
