We offers full Technology-Transfer packages, which include a comprehensive course at our facility. The company has developed a simple, cost effective and easy to implement proprietary Technology for the production of highly active bulk recombinant E.Coli derived proteins.

Each batch production at our facility is within 2-3 days and can yield 1000-2000 mg/protein.
The Technologies offered give a clear edge over the competition resulting from low production costs, high yield and production efficiency.

We are also seeking for strategic partners and alliances in the biotech and pharmaceutical field to develop and market bio-drugs according to FDA and EU pharma regulations and certification.

We offer the following recombinant technologies:
