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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-Mal-N-bis(PEG2-acid) is a thiol reactive PEG reagent. Maleimide reacts specifically with sulfhydryl groups to form a stable thioether linkage when the pH is between 6.5 and 7.5. The terminal carboxylic acids can react with primary amino groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose.
