OECD Guidelines for the Testing of Chemicals
The OECD Guidelines for the Testing of Chemicals is an internationally agreed upon collection of testing methods
used by government, industry and independent laboratories to identify and characterize potential chemical hazards.
These approved assays are testing tools used primarily in regulatory safety testing as well as, subsequent
chemical product notifications, chemical registrations and in chemical evaluations.
They can also be used for the selection and ranking during the development of new products
and chemical agents in toxicological research.

MB's Institutional Animal Care and Use Committee (IACUC) meets at least six times each year to monitor the care and use of research animals.
The committee reviews procedures, protocols and the facility to ensure that all phases meet or exceed the requirements of the Animal Welfare
Act and the Guide for the Care and Use of Laboratory Animals.
MB Research Laboratories prides itself on pursuing alternative toxicological methods that reduce, refine and replace the use of animals
in toxicological research. For over 25 years, MB has pioneered the development and validation of alternative tests with a goal on replacing
laboratory animals in toxicological research.
