NABR provides the unified voice for the scientific community on legislative and regulatory matters affecting biomedical research using research animals. NABR's membership is comprised of more than 350 public and private universities, medical and veterinary schools, teaching hospitals, patient advocacy groups, professional societies, pharmaceutical, biotechnology and other research-related companies.

NABR supports the responsible use and humane care and treatment of laboratory animals in research, education and product safety testing. Further, the membership believes that only as many animals as necessary should be used; that any pain or distress animals may experience is minimized; and that alternatives to the use of live animals should be developed and employed, wherever feasible.
