POLYPURE, the PEG designer
Polypure AS is producing high quality single-length or uniform polyethylene glycol (PEG) and PEG derivatives for advanced applications.
Monodisperse PEG linkers are used to improve solubility and pharmacokinetic properties of peptides, proteins, biopharmaceuticals and organic drug molecules.
Our PEGs are thoroughly fractionated by proprietary chromatography from polydisperse PEG to individual components. These ultrapure PEGs are no longer polymer mixtures. Our products contain less than 2% n-1 (polydispersity <1.0002).
The perfect monodispersity of our PEG reagents ensures consistent quality, product characterization and reproducibility of the results.
A broad selection of heterofunctional derivatives of PEG from MW400 range up to 5KDa can be supplied in several configurations to satisfy your needs for precision tool chemicals.
Polypure catalogue contains protected amines and amino PEG acids (Fmoc, Boc-protected), maleimido PEG and PEG thiol derivatives as well as a range of conjugation reagents from gram to multi-kilograms quantities.
