PEG in Research

Polyethlene glycol (PEG), is also known as polyethylene oxide (PEO) or polyoxyethylene (POE), depending on its molecular weight. Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological research, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation. In biological research, PEGs have can have many other applications, including the bioconjugation of cells into hybridomas for antibody production, vaccine or nanoparticle delivery, drug formulation and fluorescent labelling. 

Advantages of PEGS:

- High solubility.
- Neutral pH.
- Non-toxic.
- Low/no immunogenicity. 
- Non-specific interactions with biochemicals.
- Highly flexible and mobile.
