 | Hazard Information | Back Directory |  | [Description] 
 N-Mal-N-bis(PEG2-NHS ester) is an maleimide NHS esters. The NHS esters can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
 |  | [Uses] 
 N-Mal-N-bis(PEG2-NHS ester) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].
