Mouse Histology and Phenotyping Laboratory


The mission of the Northwestern University Mouse Histology & Phenotyping Laboratory (MHPL) is to assist investigators with tissue histopathology for experimental animal research. The laboratory provides comprehensive histology services for all rodent species (i.e., mouse, rat, etc.) which includes phenotyping consultation of organs and tissues, dissection and tissue processing, and one-on-one consultation with investigators. The lab generates unstained paraffin and frozen sections for investigators to be used for special staining and immunohistochemistry (IHC). Pathologist consultation is also available to help researchers develop strategies maximize the value of their tissue-based experiments. In addition, the laboratory provides opportunities for researchers to learn histology techniques and phenotyping analysis.

Services Offered

  • Dissection and tissue collection
  • Consultation with Animal Pathologist
  • Tissue Clearing
  • Histopathology (slide interpretation)
  • Photo documentation of histopathology
  • Training in necropsy techniques including perfusion of mice and special tissue dissection
  • Assistance with development of animal pathology protocols
  • Immunohistochemistry (IHC) – Using tyramide signal amplification (TSA) and ABC methods (automated), with DAB chromogenic substrate.
  • Immunofluorescence (IF)- Single and multiple staining
  • TUNEL assay
  • Freezing and embedding of tissues for histology
  • Frozen sections
  • Paraffin block processing and Paraffin sections
  • Hematoxylin and Eosin staining of sections
  • Specialized histochemical staining of sections (e.g. Trichrome, PAS, Luxol fast blue, Cresyl violet, and many other stains)

Members of the Lurie Comprehensive Cancer Center who require additional guidance with their projects have priority access to one-on-one consultation with Dr. Craig Horbinski, a board-certified anatomic pathologist and neuropathologist who specializes in cancer research, including animal models of cancer. Specific time for such consultations is reserved every Friday between 10-12 am in Dr. Horbinski’s office, Tarry 2-705. Appointments at other times are also available; please contact Dr. Horbinski directly at 312-503-6127 or by email at
