Cryo Storage

Cryopreserved sperm and embryos can be easily damaged by improper storage conditions. As one of the first organizations to cryopreserve mouse embryos and sperm, The Jackson laboratory has decades of experience managing cryopreserved materials. Our secure facilities are equipped with monitored and alarmed tanks overseen by experienced staff, ensuring the future recoverability of your strains.

  • Aging

  • Diet-Induced Obesity

  • Surgical

  • Timed-Pregnant Mice


Some diseases, such as Alzheimer's and cancer, develop later in life— both in humans and mice. We will age and deliver mice to you when they reach an age appropriate for your research.

Diet-Induced Obesity

Diets high in fat have been attributed to a host of diseases, including obesity, metabolic and inflammatory diseases. The Jackson Laboratory maintains an inventory of diet-induced obesity (DIO) models, and can place any strain on any fully customized diet so that your mice are ready when you need them.

Our expert surgeons are specially trained to perform surgeries on mice, using aseptic and atraumatic techniques that prevent operative complications permitting a smoother surgical recovery. All surgeries are performed in a laminar flow hood within HEPA-filtered, positive pressure suites to deliver surgically modified mice that are tailored for your specific research needs.
