ε polylysine
Manufactured by Sinopharm
ε-Polylysine is a natural antimicrobial polypeptide produced by bacteria. It is a linear homopolymer of the amino acid lysine. The ε-amino group of each lysine residue is linked to the α-amino group of the next lysine residue, forming a polyamide structure.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
