OCT.2 is a transcription factor that binds to the immunoglobulin gene and interacts with BOB.1. It is essential for expression of B-cell specific genes. OCT.2 is expressed in mature B-cells, predominantly germinal center B-cells. High levels of OCT.2 expression are also found in monocytoid B-cells and plasma cells. Various B-cell lymphomas are also positive for this marker.
Tissue-Tek Genie<sup>&reg;</sup><br /> anti-OCT.2 A strong nuclear staining reaction is observed among the neoplastic cells of this diffuse large B-cell lymphoma.

The Reed-Sternberg and Hodgkin cells of this classic Hodgkin lymphoma show a negative staining reaction for OCT.2, while background B-cells and plasma cells show moderate to strong nuclear reactivity.
