Linear Monofunctional PEGs

Nanosoft Polymers offers a broad portfolio of Linear Monofunctional PEGs with various molecular weights and terminal functional groups. These PEG derivatives contain one reactive end group while the opposite terminus is typically capped with a non-reactive group such as methoxy (mPEG), providing controlled and site-selective conjugation.

Linear monofunctional PEGs are among the most widely used PEGylation reagents in pharmaceutical, biotechnology, diagnostic, and materials science applications. They improve water solubility, increase circulation time, reduce immunogenicity, and enhance the stability of proteins, peptides, nanoparticles, and small-molecule therapeutics.
