ε-Poly-L-lysine (MW 3800-4200)  (Synonyms: Epsilon-polylysine (MW 3800-4200); ε-Polylysine (MW 3800-4200); ε-PL (MW 3800-4200))

Cat. No.: HY-W250308 Assay: 99%
COA Handling Instructions

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.

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.
