Background
FOXN1 is a member of the Forkhead box family of transcription factors, which share a conserved DNA-binding domain but differ in flanking sequences that confer target specificity. FOXN1 is essential for the development and maintenance of the thymic epithelium, where it directs the microenvironment required for T cell development, and it also regulates epithelial differentiation in skin and hair follicles. Loss of FOXN1 function causes the nude phenotype, characterized by athymia and immunodeficiency. FOXN1 transcriptional activity is studied in developmental biology, immunology, and epithelial cell research.
Product Description & Applications
The FOXN1 Reporter Lentivirus is a transcription factor reporter system built with tandem repeats of FOXN1 DNA-binding elements designed to preferentially read out FOXN1 activity over other Forkhead transcription factors. The elements drive a reporter gene downstream of a minimal promoter, giving a sensitive fluorescent or luminescent readout of FOXN1 transcriptional activity. Reporter options include EGFP, GFP, mCherry, RFP, d2GFP, and firefly luciferase, with optional blasticidin or puromycin selection for stable polyclonal cell line generation. Particles are purified by PEG precipitation and sucrose gradient centrifugation and efficiently transduce difficult-to-transfect cells, including primary and thawed cells.
It supports stable reporter cell line generation for studying thymic and epithelial development.
About This Product
This reporter lentivirus places a d2GFP, EGFP, Firefly Luc, GFP, mCherry, RFP reporter gene under the control of tandem consensus response elements specific for the FOXN1 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, Puromycin) 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.

Common customization requests
- Insert / payload: replace the gene/sequence, swap to a different isoform, add mutations, or optimize cloning features.
- Expression design: change promoter (e.g., CMV/EF1α/PGK), add enhancers, or adjust regulatory elements.
- Reporters: add/swap GFP/RFP/mCherry/luciferase (single or dual reporters where applicable).
- Selection markers: add/swap puromycin/blasticidin/neomycin or fluorescent selection options.
- Vector format: switch between OE, shRNA, CRISPR (sgRNA/Cas systems), or control vectors (where supported).
Add-ons you can request
- Control viruses: empty vector, non-targeting shRNA, reporter-only controls, or matched backbone controls.
- Packaging / format: concentration options, aliquoting, or custom fill volume for screening workflows.
- Documentation: construct map/sequence confirmation package (as available) and batch documentation.
What to include in your request
- Target cell type/model (cell line or primary cells) and intended readout (reporter, knockdown, OE, etc.)
- Insert sequence (FASTA) or reference ID, plus any required tags/mutations
- Promoter, reporter, and selection marker preferences
- Desired scale and preferred format (aliquots / concentration requests)
