Histotechnology Facility (Wistar)

Director: Gourevitch, Dmitri, M.D.


This facility provides basic histology services. These include fixing, processing and paraffin embedding of all types of tissues for light microscopy (i.e. routine stains, immunohistochemistry or in situ hybridization). Routine hematoxylin and eosin staining as well as special staining is done in the lab. Slides are prepared for immunohistochemistry and in situ and immunohistochemistry.

Frozen sectioning is also available. It is advisable to contact the facility about freezing techniques so the best sections can be obtained.






  • Frozen sectioning service ( Material processing service )

    Fixation, frozen tissue embedding and sectioning are available in the facility.

    "Cutting frozen sections is sometimes best for doing immuno staining, especially when the antigen is masked by fixation. If frozen sections are required it is advisable to schedule an appointment.

    Turnaround time for work submitted depends on the size of the project as well as the number of other projects that are being carried out at the time of submission. Often times the finished product can be obtained the next day and almost always within 3 days."

  • Histology staining services ( Material processing service )

    "Routine H&E (hematoxylin and eosin) staining is available at all times. Other special stains are done upon request. These include Trichrome for collagen, Bodians for nerve fibers, Luxol Fast Blue for myelin sheath, PAS for basement membrane and glycogen, Congo Red for amyloid, Oil Red O for fat and others that may be required for special projects."

  • Paraffin sectioning service ( Material processing service )

    Fixation (commercially bought 10% buffered formalin, Histochoice, Bouin's fixative, or specialty); decalcification (if the specimen contains bone); tissue processing and paraffin embedding; and sectioning (routinely at a thickness of 5 microns, but the thickness can be changed if requested) are available in the facility.
