Highly Pure,
Monodispersed
Polyethylene Glycol
(PEG) Products

While most PEG products are a mixture of different
molecular weights, PurePEG supplies mono-disperse,
single molecular weight molecules. Through our innovative
PurePEG TM technology, we have the ability
to manufacture high quality mono-disperse PEGs with
precise molecular weights in high purities.

WELCOME TO PurePEG

PEGs have earned their place in the biomedical field due to their
water solubility, non-toxicity, and non-immunogenicity properties.
They are widely used in research for bioconjugation, assays, and
bioorthogonal labeling purposes. To date, there are 12 PEGylated
drugs approved by the FDA for treatment of a number of chronic
diseases, with more approvals pending. PurePEG developed the
first acid functionalized PEG used in an FDA approved antibody-
drug conjugate (ADC drug) used to treat breast cancer. PEG’s
impact on biological therapies cannot be understated. Despite a
wider market of suppliers and manufacturers of PEG, PurePEG still
stands at the forefront with our unparalleled quality of PEG and
our ever-expanding PEG research and development

Supplying PEG reagents
with discrete molecular
weights, offering PEG
reagents with
up to min.99% purity
