Professor Stan Roberts is internationally known for his expertise on synthesis of poly(amino acid)s. For example, polyleucine is called Roberts' regent. Under the direction of professor Roberts, guilin peptide technology limited, formerly called guilin polylysine technology limited, own a proprietary technology for making poly(arginine, histidind, lysine) of unique quality(99.9%), economically in commercial scale.

Epsilon-polylysine (e-PL) is a homopolyamide linked by the peptide bond between the carboxylic and epsilon amino group of adjacent lysine molecules. It is biodegradable and nontoxic towards human. Most of the biomedical applications till date use toxic α-PLL as a raw material. However, it is believed that e-PL would be an ideal substitute.

We are currently the only company that can produce epsilon-polylysine by chemical synthesis. As a manufacturer, we can send small, medium and large packages as you required. We offer a special discount to our existing customers.
