Homobifunctional PEGs have the same functional reactive groups at both end of the PEG polymer chain, which can be extensively used for PEGylation of proteins, peptides, oligonucleotides, nanoparticles, bioconjugation, drug delivery and surface modifications.

Huateng Pharma offers high quality linear homobifunctional PEGs with high purity and low polydispersity.

Homobifunctional PEGs with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at sales@huatengusa.com about pricing and availability.
