How to Choose a Rat Strain for Your Research?

The laboratory rats, Rattus norvegicus, have been used in research, and their use is steadily augmented over the last decade. A laboratory mouse can be used as a biological research model in physiology, pharmacology, toxicology, immunology, theriogenology, molecular genetics, medicine, and oncology. Rats and mice are genetically characterized as distinct, and rats have a larger size to allow scientists to perform experiments. These rat models are economical in comparison with large animal models. However, sometimes obstacles increase in research work using genetically modified rats.
