Animal Histology Services

The Department of Comparative Medicine's Animal Histology Services (AHS) provides a broad range of histological techniques that include standard processing and embedding methods as well as processing of larger specimens, serial and step sectioning, sectioning of frozen specimens, and a variety of staining techniques. 

We offer special orientation of tissues to match images from MRI, CT and other imaging modalities or for unbiased stereology. In addition to routine hematoxylin and eosin (H&E) staining, we offer special stains to highlight infectious agents (bacteria, fungi), cellular elements, different cell types, and tissue matrix components. Also, we offer immunohistochemical assays.

Note: Many histological techniques are sensitive to methods that are used for fixing or freezing of tissues, and results often depend on appropriate specimen preparation.  For general questions about sample submission, please email us.


Animal Histology Service Hours:  7:00 A.M. to 3:00 P.M.
Our offices will be closed on all University Holidays.

We are continuously working to improve and expand our services. Please take our brief survey on future services of the AHS.
