Synonyms: Methoxy-PEG-Br; Methoxy polyethylene glycol-Br; Methoxy-PEG-Bromide; Methoxy polyethylene glycol-Bromide

mPEG-Br is a unilaterally active PEG derivative, which is usually used as a biomolecule modifier to modify proteins, peptides, and particles. MPEG-Br can greatly help protein and peptide drugs improve immunogenicity, half-life, stability, solubility and other properties. Depending on the molecular weight, mPEG-Br presents a solid or viscous liquid. It is soluble in aqueous solutions and most organic solvents, and a fresh solution must be prepared before use. What’s more, it must be stored in an inert gas environment below -20℃. Besides, MPEG-Br is widely used in medical research, drug release, nanotechnology and new material research.
