Several different types of mouse are used in laboratory research (e.g., the spiny mouse, the deer mouse, etc.) but the most commonly used mouse is Mus musculus, the house mouse. This is the typical white lab mouse envisioned by most. The naming system for particular inbred or genetically modified mice is complex, but the genus and species are typically the same.

The average blood volume for a laboratory mouse is ~6-8% of total body weight. So a mouse of 20g = 1.2-1.6mL. Note: you will not be able to collect this much blood as this is the total blood volume. The total peripheral blood would be ~ 60-70% of the total blood volume.
