Description and Uses

Mal-heptanoic 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.

6-Maleimidohexanoic acid N-hydroxysuccinimide ester can be used in:

• Synthesis of maleimide-activated carbohydrates for site-specific glycosylation of cysteine-containing peptides and proteins via maleimide-thiol ligation reaction.
• Synthesis of a glucuronide prodrug of doxorubicin bearing a maleimide side chain as an antitumor agent.
• Cross-linking oligonucleotides with the amino groups on the substrate to fabricate DNA microarrays.
