PEGylation Service
PEGylation is the process of covalent and non-covalent attachment or fusion of PEG polymer chains to molecules and macrostructures. The PEGylated structures result in improved solubility, enhanced molecular stability, and a slowing down of its degradation as well as elimination in vivo, making them more effective for many therapeutic applications.
Our PEGylation Service
At Creative PEGWorks, we provide generic or site-specific PEGylation of proteins, antibodies, aptamers, DNAs, small molecules, dendrimers, nanoparticles, and biodegradable polymers. We also can provide post-translational polysaccharide modification of biologics, protein lipidation, bioconjugation, and crosslinking chemistry.

PEGylation Service FAQs
What is PEGylation?
PEGylation is a process in which PEGs are covalently attached to a target molecule, such as proteins, peptides, small molecules, or nucleic acids.
What are the benefits of PEGylation?
PEGylation offers several benefits, including:
- Increased circulating half-life of the modified molecule.
- Improved stability and reduced degradation.
- Enhanced solubility and bioavailability.
- Reduced immunogenicity.
- Controlled release and targeted delivery.
- Protection against enzyme degradation.
- Improved pharmacokinetic profile.
- Reduced toxicity.
How is PEGylation achieved?
Through chemical conjugation methods, reactive functional groups on the PEG molecule, such as NHS ester or maleimide, react with specific functional groups on the target molecule to form a covalent bond. This creates a PEGylated product.
Are there any limitations or challenges in PEGylation?
While PEGylation offers numerous advantages, there can be challenges associated with the process.Â
Some limitations include:
- Maintaining the bioactivity of the target molecule after PEGylation.
- Achieving site-specific PEGylation to minimize potential interference with the target molecule’s function.
- Overcoming potential immunogenicity or hypersensitivity reactions to PEG.
- Controlling the size and distribution of PEGylation to ensure desired pharmacokinetic properties.
Are there different types of PEGylation?
Yes, there are different types of PEGylation techniques, including linear PEGylation, branched PEGylation, site-specific PEGylation, and multi-PEGylation. The choice of technique depends on the specific requirements of the target molecule and its intended application.
