Background
OCT11, encoded by POU2F3, is a POU-domain transcription factor with expression largely restricted to skin keratinocytes and chemosensory tuft cells. It binds octamer DNA motifs and drives gene programs essential for epidermal differentiation and tuft-cell identity and mucosal immune responses. POU2F3 is the master regulator of the tuft-cell-like (POU2F3-positive) subtype of small-cell lung cancer, where it cooperates with the coactivators OCA-T1 and OCA-T2 to activate transcription at POU octamer motifs. Because of its lineage-defining role in normal tissues and in this distinct cancer subtype, OCT11 is an important target in developmental biology, epigenetics, and oncology research.
Product Description & Applications
The OCT11 Reporter Lentivirus is a transcription-factor reporter system for detecting OCT11 (POU2F3)-dependent gene expression in mammalian cells. The construct uses tandem repeats of the OCT11 DNA-binding motif from the tuft-cell-specific TRPM5 gene, coupled to a minimal promoter that drives a fluorescent or luminescent reporter. A constitutively expressed selection marker and optional secondary reporter allow generation of stable polyclonal reporter cell lines with readout by microscopy, flow cytometry, or luminometry.
Stable lentiviral integration provides consistent reporter expression in dividing and post-mitotic cells, including primary and cryopreserved cultures, avoiding the variability of transient transfection. Particles are purified by PEG precipitation and sucrose gradient centrifugation and transduce difficult-to-transfect cells, supporting research on OCT11 in epithelial differentiation, tuft-cell biology, and small-cell lung cancer.
About This Product
This reporter lentivirus places a BFP2, d2GFP, EGFP, Firefly Luc, Gaussia Luc, GFP, GFP + Firefly Luc, mCherry, Renilla Luc, RFP, RFP + Firefly Luc reporter gene under the control of tandem consensus response elements specific for the OCT11 Pathway transcription factor, coupled to a minimal TATA-box promoter and a proprietary upstream enhancer that maximizes signal-to-noise. The constitutively expressed selection marker (Blasticidin, Hygromycin, Puromycin, Zeocin) and/or secondary reporter enables stable polyclonal cell line generation and flexible readout by fluorescence microscopy, flow cytometry, or luminometry.
Stable integration via the lentiviral backbone ensures consistent, clonally representative reporter expression in dividing and post-mitotic target cells — including primary T cells, macrophages, organoids, and cryopreserved material — eliminating the variability inherent to transient transfection. The self-inactivating LTR design and third-generation packaging minimize insertional mutagenesis risk and ensure biosafety classification at BSL-2.
