JAX® Speed Expansion Service
Need dozens or even hundreds of mice—all of the same age—all at a specified and opportunistic pathogen free (SOPF) status—fast? Using IVF, we routinely produce cohorts of mice that can be used to jump start a breeding colony or perform characterization studies. This saves months over traditional breeding approaches and requires only a few males from the colony to be expanded.

Key benefits
- Ideal for quickly producing large quantities of SOPF, same-age, genetically engineered mice on common genetic backgrounds

- Ideal for strains where males have short lifespan or breeding windows (e.g. neuromuscular and neurological disorders)
Capabilities
- Experience using many different inbred lines as oocyte donor strains
- Access to the female mice at the same age and quantities needed
- All mice produced are SOPF
- Can be used to expand customer colonies or to generate cohorts of JAX® Mice that are only available in limited supply
