Welcome to the IACUC – Using Rats in Research. You may not work with mice unless you are first listed on a protocol approved by the Institutional Animal Care and Use Committee (IACUC), understand the procedures approved in the protocol, and have completed this and the Barrier Facility training programs. Some of the information provided in this course is applicable to all research animals whereas other information is specific to mice. There is, therefore, some overlap between this and other courses. This course provides general information pertinent to the use of mice in research regardless of research methods and procedures. Detailed information and training on specific research procedures can be obtained from the Attending Veterinarian.
