N-Mal-N-bis(PEG4-NHS ester) Chemical Properties,Uses,Production

Description

N-Mal-N-bis(PEG4-NHS ester) is a branched maleimide linker with two terminal NHS esters. NHS esters is used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule.

Uses

N-Mal-N-bis(PEG4-NHS ester) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].

IC 50

PEGs; Alkyl/ether
