Scientific Data Images for Human POU2F3 Antibody

Detection of POU2F3 in Human Melanoma.

POU2F3 was detected in immersion fixed paraffin-embedded sections of human melanoma using Mouse Anti-Human POU2F3 Monoclonal Antibody (Catalog # MAB11625) at 5 µg/ml for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the nucleus.

Background: POU2F3

POU2F3 is a 47 kDa transcription factor involved in the regulation of the differentiation of keratinocytes. It is also a part of the POU2F3-POU2AF2/POU2AF3 complex that drives the expression of tuft-cell-specific genes. Normal and neoplastic tuft cells share a genetic requirement for POU2F3. POU2F3 is utilized as an ancillary marker for the diagnosis of neuroendocrine-low small cell lung cancer. It is also positive in mesenchymal and neuroectodermal tumors including synovial carcinoma, solitary fibrous tumor, glioblastoma, Wilms tumor and melanoma.
