ARUP Laboratories offers a wide range of immunohistochemical stains on sections cut from formalin-fixed, paraffin-embedded tissue or cell blocks. In addition to routine antibodies used for diagnostic differentiation, ARUP offers staining for a broad range of esoteric antibodies not usually available to the community pathologist. Currently, more than 200 antibodies are available, and new markers are constantly being evaluated. ARUP’s antibody menu includes markers that help determine tumor-cell lineage, as well as prognostic and therapeutic markers.
The ARUP Immunohistochemistry Laboratory is directed by board-certified pathologists who are also faculty members of the Department of Pathology at the Spencer Fox Eccles School of Medicine at the University of Utah. ARUP’s pathologists are available for consultation and assistance with selecting the appropriate markers for analysis.
