Fischer 344 rat

The Fischer 344 rat is a widely used strain of laboratory rat known for its consistent genetic traits and reliability in research. Developed in the 1930s, these rats are commonly employed in studies related to cancer, aging, and toxicology due to their predictable responses to drugs and treatments. They are particularly noted for their longevity and specific health profiles, making them ideal for long-term studies. Researchers value Fischer 344 rats for their uniformity, which helps ensure that experimental results are reproducible and applicable to broader scientific questions.
