What is N-Succinimidyl 3-maleimidopropionate?
Description
3-Maleimido-propionic NHS ester contains a maleimide group and an NHS ester. The NHS ester can be 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 with a thiol.
Chemical properties

The Uses of N-Succinimidyl 3-maleimidopropionate
A short, sulfhydryl and amino reactive heterobifunctional crosslinking reagent, N-Succinimidyl 3-maleimidopropionate can also been used in immunodiagnostics.
The Uses of N-Succinimidyl 3-maleimidopropionate
3-Maleimidopropionic acid N-hydroxysuccinimide ester is a reagent that is widely used for generating stable maleimide-activated carrier proteins that can spontaneously react with sulfhydryls. Alternatively these relatively stable maleimide-activated intermediates may be lyophilized and stored for later conjugation to a hapten.
