Immunohistochemistry Stains

The ARUP Immunohistochemistry Laboratory performs more than 175 stains on formalin-fixed, paraffin-embedded tissues/cellblocks. These stains are used to detect the presence, abundance, and localization of specific proteins to aid in determining the direction of differentiation in neoplasms with similar morphology as well as to provide prognostic or therapeutic information, among other applications.

This lab is pathologist oriented, providing a stain and return service only, without interpretation, to our client pathologists to assist in their diagnostic studies. Most stains are returned the next day. The available stains are listed under the Stain and Return Immunohistochemistry tab. If interpretation is needed, please order a consultation.

To order a surgical pathology consultation, please use test code 2013263 Consultation, Surgical Pathology or 2013258 Consultation, Hematopathology. For more information, call (801)581-2507. Please include pertinent clinical history and surgical pathology report.

The Immunohistochemistry Laboratory has a menu of immunohistochemistry tests for which we will provide interpretation by one of our ARUP faculty pathologists. A list of these tests can be found under the Immunohistochemistry Tests tab. The ARUP Immunohistochemistry Laboratory is an NSABP-approved laboratory for the testing of breast markers.

Test # Test Name Test Keywords Test Description
2008716 Napsin A by Immunohistochemistry
  • Napsin A is highly specific in adenocarcinomas of lung and is useful in distinguishing primary lung adenocarcinomas from adenocarcinomas of other organs
  • The pattern of reactivity is cytoplasmic
2004049 Neurofilament by Immunohistochemistry Tumor Markers
  • Cytoskeletal element in nerve axons/dendrites
  • Reacts with neurons, neuronal processes, peripheral nerves, sympathetic ganglion cells, and adrenal medulla
  • Identifies neuroblastoma and gangliomas
2004052 Neuron Specific Enolase, Polyclonal (NSE P) by Immunohistochemistry Neuroendocrine Marker, neuronal or neuroendocrine cells and their tumors: neuroblastomas and retinoblastomas Neuron-specific enolase:
  • Expressed by neuronal or neuroendocrine cells and their tumors: neuroblastomas and retinoblastomas
  • May label non-neuronal tumors: meningiomas, medulloblastomas, astrocytomas, glioblastomas, oligoastrocytomas, oligodendrogliomas, pituitary adenomas, schwannomas, ependymomas, meningosarcomas, gliosarcomas, small cell lung cancer, melanomas, and germ cell tumors
2004046 Neuronal Nuclei (NeuN) by Immunohistochemistry
  • Aids in the definitive identification of neuronal elements in ganglion cell tumors or hamartomas, in which a distinction between atypical glial cells and neurons may be difficult.
  • May be used, similarly, for the study of neuronal loss in epilepsy, neurodegenerative diseases, or other conditions
