PEG-ATRP, PEG-Bib, Dibromoisobutyryl PEG

Description

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 applications, 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.

Molecular Weight

PEG average Mn 300 (n ~ 7)
average Mn 700

Application

PEG functionalized with bromoisobutyryl group to initiate atom transfer radical polymerization (ATRP). This macroinitiator can be used to increase biocompatibility; hydrophilicity; or generate a triblock copolymer with PEG as the middle block.
