Automated differential staining for cartilage and bone in whole mount preparations of vertebrates.
An automated, rapid procedure for differential staining of cartilage and bone of vertebrates is described. The process involves rapid, complete staining of freshly skinned, eviscerated specimens after 30 sec immersion in a 70 C water bath, fixation in formol acetic alcohol and a rinse in 70% alcohol. Using an automatic tissue processor, the specimen is stained in alcian blue for 24 hr and macerated in 3% potassium hydroxide for 8 hr. Staining in alizarin red with maceration in 3% potassium hydroxide is completed manually. The specimens are cleared and preserved in glycerol. Good quality evenly stained specimens can be examined in less than three days and up to 600 fetuses can be processed in less than five days.
