Abstract
A simple three-day technique is described for preparing completely cleared and high quality alizarin stained total skeletons of adult mice. Unfixed specimens are partially macerated during staining. Older specimens are heated for 15 min in 1% KOH. A heated solution of benzyl and ethyl alcohol, glycerin, and water is used for final clearing and hardening. This procedure requires about 10 min work per specimen and greatly simplifies preparation of stained and cleared skeletons of adult mice. Another technique, giving slightly better preparations, but requiring 11-14 days, is also described.
