Small but mighty!
The future in veterinary vaccines is within reach
Learn how we are getting there
Beginnings and early steps
2016
We began working in contract R&D services in biotechnology with a One Health approach, implementing a level 2 biosafety laboratory (BL2) for bacteriology and virology. We developed capabilities for upstream and downstream biological processes for companies in Latin America, Europe, and the Middle East.
2017
We began the developing and marketing toxin and antitoxin standards, quality control of veterinary biologics according to USP and Ph. Eur standards.
Leaps and bounds
2018
We were singled out as the leading start-up company in biotechnology innovation (NOVA Award, of the National Agency for Research and Innovation (ANII)), and as the main small to medium-sized enterprise exporting biotechnology services (Uruguayan Union of Exporters and the Banco República Oriental del Uruguay (UEU and BROU)).


Forward is the only way
2021
We have solidified our position as a key partner for the development of new products and process optimization for high-level companies with subsidiaries in Brazil, Argentina, Uruguay, Colombia, Guatemala, and Turkey.
2022
We constantly advance in several treatment and diagnostic projects based on recombinant single-domain antibodies and develop a new generation of in vitro assays for the quantification of antigens based on single-domain antibodies. Benten Biotech grows stronger in the quality control of veterinary biological products: we provide standardized reagents to various countries and carry out outsourced potency tests of vaccines, and also transfer turnkey production technologies and train the quality control teams of other companies.
Meet our team!
We are highly motivated and have a broad range of backgrounds and interests, all sharing extensive experience in the development of biologics.
