Identifies a transcription factor involved in oligodendroglial specification and development. It is expressed in most glial tumors, including oligodendrogliomas and astrocytomas, but is negative in non-glial tumors such as ependymomas, medulloblastomas, CNS lymphomas, meningiomas, schwannomas, atypical teratoid/rhabdoid tumors, and hemangioblastomas.
Tissue Block: Formalin-fixed, paraffin-embedded (FFPE) tumor block preferred.
Unstained Slides: Recommended 2 charged slides per stain requested (minimum of 1 slide per stain), baked or unbaked.
Fixation: Tissue must be fixed in 10% neutral buffered formalin for 6–72 hours.
