Methoxy PEG Aldehyde

Linear PEGs with Aldehyde from JenKem Technology are reactive towards the N-terminal amines on proteins. Methoxy PEG Propionaldehydes react at pH 5-8 in the presence of a reducing reagent. M-ALD-20K is a suitable PEG raw material for applications such as Pegfilgrastim PEGylated biosimilars.

Aldehyde-containing PEGylation products with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at about pricing and availability of custom PEGylation products.
