PEGylation Feasibility Studies


PEGylation is an established delivery system for biopharmaceuticals, such as peptides, proteins, antibody fragments, aptamers, domains and other biologics. PEGylation can significantly improve the pharmacological and physicochemical properties of drugs.
NOF, together with our partner Celares, can support your PEG-drug development work at a reasonable timeline and cost.

 

Scope of work

  • Investigation of PEGylation strategies
  • Screening of different PEG-reagents
  • Development of reaction conditions
  • Development of purification methods
  • Preparation of PEG-drug conjugates
  • Characterization of PEG-drug conjugates

 

Deliverables

  • PEG-drug conjugates for in-vitro and in-vivo testing
  • Certificates of Analysis for conjugates
  • Final report

 

 

 

Requirements and time lines

  • 25 - 50mg of the biopharmaceutical
  • Typical feasibility studies take 1.5 months.

Advantages of PEGylation

 

PEGylation technology can be used for modifying biological compounds such as cytokines, antibody fragment, interleukins, hormones, oligonucleotides and some of proteins and peptides.

 

PEGylation can be effective in :

  • Improving Bioavailability
  • Prolonging Blood Circulation
  • Maximizing Pharmacokinetics
  • Lowering Immunogenicity
  • Decreasing Frequency of Dosing

NOF provides high-performance activated PEGs for PEGylated drugs from early development stage to commercial use. We have over 20 years of experience manufacturing high-quality methoxy polyethylene glycol, a key starting material of activated PEG in the pharmaceutical field. Our activated PEGs have a narrow polydisperity and a low diol content with a wide range of molecular weight, ranging from 2kDa to 80kDa.
