The albino laboratory mouse is an iconic model organism for scientific research in a variety of fields. An SCID. Intermediate coat colour. Kept as a pet. 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 ...
BALB/c. 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. [1]
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 ...
It is the most widely used "genetic background" for genetically modified mice for use as models of human disease. They are the most widely used and best-selling mouse strain due to the availability of congenic strains, easy breeding, and robustness. [1] The median lifespan of C57BL/6 mice is 27–29 months and the maximum lifespan is about 36 ...
Systematic inbreeding and maintenance of inbred strains of laboratory mice and rats is of great importance for biomedical research. The inbreeding guarantees a consistent and uniform animal model for experimental purposes and enables genetic studies in congenic and knock-out animals. In order to achieve a mouse strain that is considered inbred ...
Breeding experiments to study evolution and genetics. Laboratory mice, flies, fish, and worms are inbred through many generations to create strains with defined characteristics. [201] These provide animals of a known genetic background, an important tool for genetic analyses.
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 .
Behavior. FVB mice show above average activity and anxiety. [3] Because of their visual impairment, they do not show normal circadian rhythms. [4] For the same reason, they struggle with visual tasks such as the Morris watermaze. Some studies suggest the presence of non-visual cognitive impairment in other tasks such as fear conditioning.
