Contract research service

We offer sophisticated contract research services based on a wide scholarship and experiences piled up.

Non-clinical experimental services for developmental products are carried out by our staffs learned a wide scholarship and piled up rich experiences. Contract studies are strictly conducted in compliance with GLP regulation of authorities and various guidelines.

Remarkably, unique medium-term carcinogenesis bioassay models are well assessed as capable of predicting chemical carcinogenicity in a relative short-term, and investigating a candidate substance for anti-carcinogenicity. Contract studies are conducted by fully utilizing our toxicological and pathological ability. We are looking forward to receiving your contact.
