The laboratory mouse or lab mouse is a small mammal of the order Rodentia which is bred and used for scientific research or feeders for certain pets. Laboratory mice are usually of the species Mus musculus. They are the most commonly used mammalian research model and are used for research in genetics, physiology, psychology, medicine and other ...
BALB/c is an albino, laboratory-bred strain of the house mouse from which a number of common substrains are derived. Now over 200 generations from New York in 1920, BALB/c mice are distributed globally, and are among the most widely used inbred strains used in animal experimentation.
By far the most popular laboratory rodent, the C57BL/6 mouse accounts for 1 ⁄ 2 to 5 ⁄ 6 of all rodents shipped to research laboratories from American suppliers. [1] Its overwhelming popularity is due largely to inertia: it has been widely used and widely studied, and therefore it is used even more.
The house mouse is best identified by the sharp notch in its upper front teeth. House mice have an adult body length (nose to base of tail) of 7.5–10 centimetres (3–4 in) and a tail length of 5–10 cm (2–4 in). The weight is typically 11–30 g (8 –1 oz). In the wild they vary in color from grey and light brown to black (individual ...
Laboratory rats or lab rats are strains of the rat subspecies Rattus norvegicus domestica (Domestic Norwegian rat) which are bred and kept for scientific research. While less commonly used for research than laboratory mice , rats have served as an important animal model for research in psychology and biomedical science .
This is attributable to breeding and different conditions in the wild. The best-known strain of mouse is the white lab mouse. It has more uniform traits that are appropriate to its use in research. Cats, wild dogs, foxes, birds of prey, snakes and certain kinds of arthropods have been known to prey upon mice. Despite this, mice populations ...

Oncomouse. The OncoMouse or Harvard mouse is a type of laboratory mouse (Mus musculus) that has been genetically modified using modifications designed by Philip Leder and Timothy A Stewart [1] of Harvard University to carry a specific gene called an activated oncogene (v-Ha-ras under the control of the mouse mammary tumor virus promoter).
