The OHSU Immunohistochemistry Laboratory offers a menu of more than 150 immunohistochemical stains on formalin-fixed, paraffin-embedded tissue (see searchable list). The majority of these studies are performed on Ventana automated immunostainers. The lab also uses these instruments for in situ hybridization tests. In addition, the lab offers a muscle panel, comprised of a dozen immunohistochemical stains on frozen muscle tissue. The OHSU Immunohistochemistry Laboratory performs Her-2/neu immunohistochemical testing per ASCO/CAP guidelines, and cases are sent to the OHSU Cytogenetics Lab for her-2/neu FISH testing. The laboratory also performs immunofluorescent staining of frozen tissue of medical and transplant renal cases. Technical assistance with renal biopsies may be scheduled by calling 503 494-5755. Twenty-four hour advance notice is required. The lab is open 8am-5pm Monday through Friday in Dillehunt Hall Room 5049.
