BRMS Mouse Breeding Core & Research Services


The Biomedical Research Model Services (BRMS) Program facilitates animal research across the UW campus providing animal care in 10 vivaria and services through Core Units.  The Breeding Core performs animal husbandry to supply researches with needed animals in a timely and cost-effective manner; the Research Services Core performs a wide variety of technical procedures.  Staff commonly breed mice for specific projects, perform studies inside the BRMS core facility, and deliver end point tissues or transfer live mice to laboratories after techniques are performed. Support ranges from a small portion of study to a complete study with final results.
