Polydispersed PEGs

Polydispersed PEG refers to PEG molecules with a range of molecular weights rather than a single, specific weight. 

PEGs can be classified based on their functional groups and the number of reactive sites they possess. The three main classifications are Heterobifunctional PEGs, Homobifunctional PEGs, and Monofunctional PEGs.


Polydispersed PEGs provide a versatile toolkit for researchers and practitioners in the fields of biotechnology, pharmaceuticals, and materials science.

Biopharma PEG provides polydispersed PEG linkers with an extensive variety of functional groups from gram to kilogram batch size or large commercial scale in both non-GMP and GMP grade, such as mPEG-pALDOH-PEG-AA, mPEG-EPO etc.
