The Bio F1B Hybrid is genetically-defined hamster, derived from two highly inbred lines, namely by crossbreeding between Bio 87.20 female with a Bio 1.5 male. The Bio F1B hamsters have been used in research since early 1980's. Initially the Bio F1B was used as a genetically defined control for cardiomyopathic and myopathic hamsters. Later, the Bio F1B became an exciting animal model for hyperlipidemic-related applications.
These hamster have a relatively large body size and lifespan. They are also rigid and can withstand surgical procedures well.
