Description

Description

CA(PEG)n is the abbreviation for a set of compounds having polyethylene glycol (PEG) spacers with carboxy (-COOH) and amino (-NH2) termini. The unbranched, hydrophilic, discrete-length molecules have the form Carboxy-PEGn-Amine, where the subscript “n” denotes 4, 8, 12, or 24 ethylene glycol units. The carboxyl and primary amine of each compound provide specific targets for crosslinking and other conjugation methods, making these compounds useful as PEGylation reagents.

Highlights:

  • Fully characterized PEGylation reagents with defined PEG chain lengths; molecules of discrete molecular weight for consistency of performance in protein-modification applications
  • Provided as a series of 4, 8, 12 and 24 ethylene glycol units, enabling modification procedures to be optimized for a specific application while retaining all the benefits associated with protein PEGylation
  • PEG spacer provides unique advantages, including increased stability, reduced tendency toward aggregation and reduced immunogenicity
  • Allows site-specific labeling or crosslinking involving primary amines or carboxyl groups on proteins or surfaces
  • Easy-to-follow instructions increase the likelihood of a successful outcome
