Histology Core Facility

The Histology Core Facility enables researchers to prepare tissue specimens for paraffin embedding, paraffin sectioning, plastic sectioning, cryosectioning, vibratome sectioning, and histological stains. It also provides technical assistance and training in histological techniques to investigators throughout Viikki and the University of Helsinki.

The facility is equipped with 2 cryostat workstations (cryostat, microsope), 6 microtome workstations (microtome, microsope, water bath), 1 vibratome workstation (vibratome, microsope), 2 automated tissue processor machines for paraffin, 1 manual paraffin embedding station, 1 oven for manual paraffin processing, and 2 manual slide staining workstations.

As a next step for fast and high-quality analysis of stained sections, we provide high-throughput, brightfield scanning service for your microscopy slides in our BI Histoscanner facility (https://www2.helsinki.fi/en/infrastructures/histotechnology-and-laboratory-animal-pathology/infrastructures/bi-histoscanner).

Additional services are also available in our HiLAPS platform (https://www.helsinki.fi/en/infrastructures/histotechnology-and-laboratory-animal-pathology).

-All available equipments at the facility can be booked using Excel reservation file (one worksheet per room), by indicating both your name AND PI/group name: Histolab_Booking.xlsx

-New users of the facility must participate to a hands-on training session (tissue processing & sectioning) before starting using the equipment. Please contact directly our technician Julia (julia.eymann@helsinki.fi) to arrange a time for a training and/or for services.
