  • Vibratome sectioning
  • H&E staining and special staining (such as Gram, Giemsa, Ziehl-Neelsen, PAS, Luxol Fast Blue with Nissl or PAS contrast, Masson's Trichrome, Nissl, Perls, Carstair's Method, Luna stain and others)
  • Training for new users in sample preparation
  • Training for new users in cryostat sectioning

  • Planning and implementation of different and new histological techniques including Immunohistochemistry
  • Project discussion with the Pathologist
  • Results analysis

How to use the service

  1. Technical Service Requests: should be made through the HelpDesk by opening a task and filling the "Service Request Form" (SRF) when delivering samples or when request-ing counseling. (https://webint.igc.gulbenkian.pt/helpdesk/). Help in completing the SRF can be provided for first time users;
  2. Cryostat and vibratome: usage requires booking online. Induction/training is mandato-ry for first time users before obtaining booking permission (https://agendo.cirklo.org/igc/);
  3. Pathologist consultation: People are strongly encouraged to book a consultation with our Pathologist (Alistair Robson) prior to the planning of a project that involves histo-logical analysis. The project's aims and methods can be discussed and recommenda-tions made in order to successfully address the research question of interest. Online requisition should be properly filled and submitted prior to sample delivery (https://webint.igc.gulbenkian.pt/helpdesk/);

Similarly, researchers can schedule appointments for guidance in the histological in-terpretation of their samples (https://webint.igc.gulbenkian.pt/helpdesk/). Finally, fol-lowing completion of the project, the results and/or any issues that arose in the final histological analysis can be reviewed.


  • Users should provide boxes for storage of unstained slides when delivering samples.
  • Researchers will be notified by e-mail, through the HelpDesk, as soon as the work is completed, and the slides can be collected from the technicians in the lab.
  • Material should not be stored at the HU for more than 30 days.
  • When the work is for pathology assessment the slides will be immediately re-directed to the pathologist (be sure to include all details regarding experimental setting and ex-pected outcome of the pathology assessment in the request form or contact the pathologist).
