Epsilon-polylysine is an antimicrobial peptide that can be produced by bacteria such as Streptomyces. Epsilon-polylysine inhibits the growth of microorganisms such as bacteria, yeasts and molds and is therefore often used as a green food additive and preservative in various food and beverage products. Epsilon-polylysine has a variety of properties, including thermal stability, resistance to acidic conditions, and broad-spectrum antimicrobial activity. Epsilon-polylysine can be loaded on other materials to form nanoparticles or form nanofiber membranes for targeted delivery to exert sustained antibacterial efficacy. Epsilon-polylysine is also used as a liposome stabilizer .

Target:  

Endogenous Metabolite

Research Areas:  

Others

Clostripain (Clostridiopeptidase B) is a thiol protease isolated from Clostridium histolyticum. Clostripain exhibits proteolytic activity as well as amidase-esterase activity. The specificity of Clostripain is primarily restricted to arginine residues, but it also shows minor hydrolytic activity toward most lysine-containing substrates. Clostripain catalyzes the ammonolysis of Carbobenzoxyarginyl methyl ester to generate various dipeptides .

Cat. No.: HY-158228
Synonyms: PLMA
Poly-L-lysine Methacryloyl (PLMA) is methacrylated polylysine. When Poly-L-lysine Methacryloyl is cross-linked on polyetheretherketone (PEEK) through UV-induced cross-linking, it can improve the hydrophilicity of PEEK and retain its own degradation bioinertness . Poly-L-lysine Methacryloyl needs to self-assemble into fibrous hydrogel under the action of photoinitiator LAP (HY-44076), and target bioactive adhesion sites, play an inherent supporting role for tissue cells and biodegradable activity.
Application: cell culture, biological 3D printing, tissue engineering, etc.

Thiol-modified magnetite nanoparticles are prepared via high-temperature pyrolysis and surface-modified with thiol functional groups. Magnetite is widely used in magnetic resonance imaging, magnetic separation, targeted drug delivery, tumor hyperthermia, cell labeling and separation, as a contrast agent, and in retinal detachment repair surgery due to its stable properties, good biocompatibility, high strength, and lack of toxicity. It is also used as a catalyst carrier, microwave absorbing material, and magnetic recording material. Xianfeng has developed numerous derivatives of magnetite, including oleic acid-modified magnetite, magnetite with different PEG ends, DMSA-modified magnetite, polylysine-modified magnetite, carboxylated dextran-modified magnetite nanoparticles, streptavidin-modified magnetite particles, thiol-modified magnetite magnetic nanoparticles, and polyethyleneimine (PEI)-modified magnetic magnetite nanoparticles, among others.
