Our Histology Services include:

Necropsy & Gross Dissection:

Send us your fixed animals for our organ gross dissection and cassetting service.  Prices are per animal.

Paraffin Processing and Embedding: 

We accept tissues in cassettes or ones that need to be cassetted. They are processed on 1 of 2 fully automated tissue processors.  After processing, we embed your tissues in fresh high quality paraffin.

Cryogenic Processing and Embedding:

Send us your fresh tissues (rush) to be processed in an isopentane, liquid nitrogen slurry. Once this is done, we embed in OCT, prior to cutting on the cryostat. We also accept pre-embedded OCT tissues sent on dry ice for cryostat sectioning.


Both paraffin and cryostat sectioning are performed on every type of tissue, mammal, amphibian, reptile, birds.

Tissues, stents, bone or devices appropriately fixed if necessary are processed and embedded in GMA or MMA epoxy for sectioning, staining and microscopy.


Slides made by us from your tissues or sent pre-cut are stained using routine (H&E) and or special staining techniques.  All our stains are made, in house and have been modified by us for optimal tissue viewing characteristics.  All Please see our special stains list for your desired target tissues.  We also work up any stain you are familiar with and would like to use (ask).

Leica CM 3050 Cryostat
Antibody staining:

Immunohistochemistry (IHC) and Immunofluorescence (IF) antibodies are done at our facility .  If you have a target protein and would like to test for it using antibodies, we may already have a working protocol.  If we do not have a protocol, we may be able to find one or we can do a series of different tests to discern the best procedure (Discovery).  Please give us a call for more information.

Tissue Micro Array (TMA):

Both paraffin and fresh tissue services are available for making TMA blocks from your existing tissues. We use a new system for making TMA blocks that is less time-consuming and does not use the traditional tools and equipment.  This allows us to charge less and offer faster turnaround times.

Positive Control Slides:

Tonsil controlsWe have abundance of normal and abnormal human tissues.  These tissues are used by us for our special stain and IHC controls everyday.  Now you too have access to these high quality tissues.  See our affiliate website for tissue types and pricing.

Macro & Microscopic Photographs

There are 6 microscopes with different camera set-ups that take high quality photographs of tissues under glass or not.  All of our pictures are of TIFF quality, each picture being about 14 megabytes.   3 microscopes are fluorescent capable with 1 being ultrahigh quality.
