Toxicology Services

Built on more than 50 years of experience, Sinclair Research offers Toxicological research services to support biopharmaceutical, animal health and medical device development programs. Sinclair offers expertise in all research models and is a pioneer in miniature swine research.

Sinclair Research provides a wide range of nonclinical toxicology services (GLP and non-GLP) to support the clinical development of your therapeutic.  We have experience with the standard laboratory species (rats, mice, dogs, monkeys, and minipig) as well as rabbits, hamsters, and other species.  We are experienced in handling small molecules, peptides, antibodies, proteins, antibody drug conjugates, and viral vectors that are being developed for indications from oncology to neuroscience to animal health with deep expertise in dermal toxicology and regulatory expectations for development of small molecules and biopharmaceuticals. Our technicians are experienced using most routes of administration (with the exception of inhalation). Sinclair has board certified toxicologists on staff to help you determine the best nonclinical program for your therapeutic and ensuring it meets regulatory expectations.
