Instruction de manipulation Technical Support

N-(2-Aminoethyl)maleimide (2-Maleimidoethylamine) hydrochloride is a selective covalent binding agent for thiol groups (RSGs), covalently binding to thiols via an irreversible thioether bond to prepare MMP-2-sensitive nanosystems. Under near-neutral conditions, the maleimide group in N-(2-Aminoethyl)maleimide hydrochloride binds to thiol groups via a nucleophilic addition reaction, and can be used to modify polymers or biological interfaces, enhancing mucosal adhesion and regulating the surface charge of biological interfaces. N-(2-Aminoethyl)maleimide hydrochloride can optimize the adhesion performance of drug delivery carriers and cell interactions with biological interfaces, and is applied in transmucosal drug delivery systems (such as drug carriers for oral and bladder sites) and biomaterial surface engineering research, providing support for tissue implantation, regeneration, and related drug delivery.

Under near-neutral conditions, the maleimide group in N-(2-Aminoethyl)maleimide hydrochloride binds to thiol groups via a nucleophilic addition reaction, and can be used to modify polymers or biological interfaces, enhancing mucosal adhesion and regulating the surface charge of biological interfaces.

In Vitro

N-(2-Aminoethyl)maleimide hydrochloride (AEM·HCl) functionalized CMC material (CMC-MAL) exhibits improved biocompatibility and mucoadhesive properties[1].
Low cytotoxicity: In a human gingival fibroblast (HGF-1) model, after 24 hours of treatment with CMC-MAL at concentrations of 0.1-5000 μg/mL, the relative cell viability exceeded 80%, with no significant differences in toxicity and no apparent trend of cell damage. Basis for biosafety: CMC is a commonly used excipient in the pharmaceutical industry and has been proven to be biocompatible. AEM·HCl modification did not introduce toxicity, and its cytocompatibility was not significantly different from unmodified CMC. N-(2-Aminoethyl)maleimide hydrochloride (AEM·HCl) functionalized CMC material (CMC-MAL) exhibits improved mucoadhesive properties[2].
1. Strong and persistent adhesion: Flow-through analysis showed that over 40% of the polymer remained on the mucosal surface after 1 hour of washing, while less than 30% of unmodified CMC remained. 2. Strong adhesive force: The viscosity of a mixture of 5% CMC-MAL and 5% mucin was 1.4 times that of 5% CMC + mucin. The maximum peel force and total adhesion work of CMC-MAL were significantly higher than those of unmodified CMC and chitosan (a first-generation mucoadhesive polymer). 3. Clear mechanism of action: Irreversible adhesion is achieved through the formation of covalent thioether bonds between the maleimide group and the thiol groups in the cysteine-rich domains of mucin; after pretreatment of the mucosa with cysteine, the adhesion force of CMC-MAL decreased significantly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
