WebThermo Scientific Pierce CA (PEG) 4 is a representative carboxyl-amine pegylation reagent. It is a pegylated amino acid of the form carboxy-PEG-amine, containing 4 polyethylene glycol units, and is useful for a variety of surface- and molecule-pegylation applications. PEG, PEO, and POE refer to an oligomer or polymer of ethylene oxide. The three names are chemically synonymous, but historically PEG is preferred in the biomedical field, whereas PEO is more prevalent in the field of polymer chemistry. Because different applications require different polymer chain lengths, PEG has tended to refer to oligomers and polymers with a molecular …
