Mal-NH-PEG4-OtBu (Mal-Amido-PEG4-t-butyl ester) is a monodispersed PEG derivative containing a maleimide group and a t-butyl ester group. The PEG spacer increases the water solubility of the resulting compound. The t-butyl protected carboxyl group protected can be deprotected under acidic conditions. The maleimide group reacts specifically with the thiol group to form a covalent C-S bond, allowing it to be biologically linked to thiol-containing molecules.
Biopharma PEG provides high purity monodisperse (discrete) PEG with an extensive variety of functional groups(such as Mal-Amido-PEG4-t-butyl ester), from grams to kilogram, even tons batch size in both non-GMP and GMP grades.
