Histology is the study of cells at the microscopic level. Most cells are colourless and transparent so sections are stained to allow particular structures and components to become visible. By examining the detailed structures of cells and their formation into tissues and organs, pathologists gain information to allow the detection of disease.

Marine Scotland Science's histology laboratory offers a comprehensive service for light microscopy including:

  • tissue fixation
  • paraffin and resin tissues processing including Rapid Microwave Histoprocessing
  • embedding
  • microtomy
  • cryotomy of frozen tissue
  • routine and special staining


Histopathology involves the microscopic examination of tissues to detect abnormalities and signs of disease, allowing the detection of a wide range of both infectious and non-infectious diseases.

Marine Scotland Science provides an experienced histopathological diagnostic service for the investigation of both wild and farmed finfish, shellfish and crustacean diseases, including a detailed pathology analysis and reporting for:

In addition, there is a comprehensive physical and electronic slide archive containing reference material for a wide range of diseases and conditions in many species.
