A number of antibodies against intermediate filaments, such as neurofilament, snail, and several laminins and keratins, are also available from the service unit. The antibodies were originally developed by Prof. Ismo Virtanen and his group. The antibodies are produced in mouse cell lines and are supplied as a supernatant.

The hematoxylin-eosin staining is made in the automated system Tissue-Tek DRS that can process 40 slides in one go.

For the immunohistochemical stains user needs to provide samples, antibodies and protocols. A test run to determine the appropriate dilution of new antibodies is recommended before a full-scale experiment.
