Vendors: Mice obtained from The Jackson Laboratory.
Health status report: The Jackson Laboratory Diagnostics Laboratory routinely monitors and documents animal health status using statistically valid sampling procedures and standard protocols. Detailed health status reports for each animal room represented from this project are on file and available on request .
See JAX®Mice Quality Control Programs
or the JAX®Mice Catalog for the list of agents monitored.
Environment before shipping:
Feed: Most strains maintained on a 6% fat diet (Purina 5K52) except the following strains maintained on a 4% fat diet (Purina 5K54): DBA/1J, NZW/LacJ, and MOLF/EiJ. WSB/EiJ alternates weekly between 4% and 11% (Purina 5K20) fat formulations.
Water: Adjusted with hydrochloric acid to pH 2.8-3.1 and supplemented with menadione sodium bisulfite (final concentration 0.4 mg/mL) to compensate for potential decrease in vitamin K activity upon autoclaving; water supplied in pinhole type bottles (Thoren Caging Systems, Inc. Hazelton, PA).
