Application

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.

We have previously reported that ovalbumin (OVA) coupled with liposome via glutaraldehyde (GA) induced OVA-specific- and IgE-selective unresponsiveness in mice. In this study, OVA-liposome conjugates were made using four different coupling protocols: via GA, N-(6-maleimidocaproyloxy) succinimide (EMCS), disuccinimidyl suberate (DSS)
