Background InformationPOU domain, class 2, transcription factor 1 (UniProt P14859; also known as NF-A1, Oct-1, Octamer-binding protein 1, Octamer-binding transcription factor 1, OTF-1) is encoded by the POU2F1 (also known as OCT1, OTF1) gene (Gene ID 5451) in human. Oct-1 belongs to the family of octamer transcription factors characterized by their binding to the ATTTGCAT octamer sequence via their POU domain (a.a. 280-354 of human Oct-1). Oct1 is widely expressed in adult tissues, however, Oct-1 knockdown has little impact on cell growth and viability in culture. Oct-1 controls multiple stem cell phenotypes in normal and tumor cells. Oct-1 promotes resistance to genotoxic and oxidative stresses in stem cells. Loss of Oct-1 antagonizes oncogenic transformation in vitro and tumorigenicity in vivo.

Applications
ApplicationAnti-Oct-1 Antibody, clone YL15, Cat. No. MAB5434-C, is a mouse monoclonal antibody that detects octamer-binding protein 1 (Oct-1) and has been tested for use in immunocytochemistry, immunohistchemistry (Parffin), Immunoflouroesencece, Western blotting, and Chromatin Immunorecipitation.
Key Applications
  • Western Blotting
  • Immunocytochemistry
  • Immunofluorescence
  • Immunohistochemistry (Paraffin)
  • Chromatin Immunoprecipitation (ChIP)
Application NotesImmunocytochemistry Analysis: 5.0 µg/mL from a representative lot detected Oct-1 cellular localization in human A431 and HeLa cells by fluorescent immunocytochemistry.
Western Blotting Analysis: A representative lot detected Oct-1, but not Oct-2, Oct-4, or Oct-6 in various human cell lysates and nuclear extracts (Maddox, J., et al. (2012). PLoS Genet. 8(11):e1003048).
Western Blotting Analysis: A representative lot detected Oct-1 in Burkitt lymphoma cells (BJAB and Namalwa), as well as a panel of six primary effusion lymphoma (PEL) cells (Di Bartolo, D.L., et al. (2009). J. Virol. 83(9):4308-4315).
Immunofluorescence Analysis: A representative lot detected Oct-1 immunoreactivity in paraformaldehyde-fixed human and mouse frozen colon tissue sections by fluorescent immunohistochemistry (Maddox, J., et al. (2012). PLoS Genet. 8(11):e1003048).
Immunohistochemistry Analysis: A representative lot detected Oct-1 immunoreactivity in formalin-fixed, paraffin-embedded human colon tissue sections (Maddox, J., et al. (2012). PLoS Genet. 8(11):e1003048).
Chromatin Immunoprecipitation (ChIP) Analysis: A representative lot detected Oct-1 occupancy at the ORF50 promoter, using stable Oct-2-inducible primary effusion lymphoma (PEL) cell line BC1/Tet-on/Oct-2. The association decreased upon induction of Oct-2 expression and enhanced upon ORF50 transfection (Di Bartolo, D.L., et al. (2009). J. Virol. 83(9):4308-4315).
Chromatin Immunoprecipitation (ChIP) Analysis: A representative lot detected Oct-1 occupancy at the U6 and U1 promoter regions in exponentially dividing HeLa cells (Zhao, X., et al. (2001). Mol. Cell. 7(3):539-549).
Electrophoretic Mobility Shift Assay (EMSA): A representative lot caused a supershift of radiolabeled OCT1 consensus oligonucleotide-bound complex in the nuclear extracts from Burkitt lymphoma cells BJAB and Namalwa (Di Bartolo, D.L., et al. (2009). J. Virol. 83(9):4308-4315).
Immunocytochemistry Analysis: A representative lot detected Oct-1 cellular localization in human diploid fibroblast MRC-5-derived HuS-L12 cells at various population-doubling levels (PDLs), as well as in the corresponding immortalized IML12–4 cells by fluorescent immunocytochemistry (Imai, S., et al. (1997). Mol. Biol. Cell. 8(12):2407-2419).
Immunoprecipitation Analysis: A representative lot immunoprecipitated Oct-1 from HEK293 cell lysates (Lai, J.S., and Herr, W. (1992). Proc. Natl. Acad. Sci. U. S. A. 89(15):6958-6962).
