Background
SIX1 (sine oculis homeobox homolog 1) is a homeodomain transcription factor of the SIX family that acts as a key regulator of embryonic development. SIX1 directs the formation of muscle, kidney, inner ear, and other tissues and promotes the self-renewal of progenitor cell populations. It can function as a transcriptional activator or repressor depending on its cofactors, partnering with Eyes absent (EYA) proteins, which enhance its activity, and with Groucho-family repressors. Many disease-associated SIX1 mutations cluster in its SIX domain or homeodomain, impairing protein interactions or DNA binding. Reactivation of SIX1 in adult tissues is associated with tumor progression, and hyperactive SIX1 and SIX2 are linked to Wilms tumor, making SIX1 an important factor in developmental biology and cancer research.
Product Description & Applications
The SIX1 Reporter Lentivirus is a transcription factor reporter system that provides a sensitive fluorescent or luminescent readout of SIX1 transcriptional activity in mammalian cells. The construct contains tandem repeats of the MEF3 site from the Myogenin promoter, placed upstream of a minimal promoter driving the reporter gene, with an optimized upstream enhancer that maximizes signal-to-noise. A constitutive drug selection marker (Hygromycin, Zeocin, Puromycin, or Blasticidin) enables generation of stable polyclonal reporter cell lines. Stable lentiviral integration provides consistent reporter expression suitable for fluorescence microscopy, flow cytometry, or luminometry. Supplied as high-titer particles purified by PEG precipitation and sucrose gradient centrifugation, the product is well suited to studying SIX1 activity in primary and difficult-to-transfect cells for developmental and cancer research.
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 SIX1 transcription factor, coupled to a minimal TATA-box promoter and a proprietary upstream enhancer that maximizes signal-to-noise. The constitutively expressed selection marker (Hygromycin, Zeocin, Puromycin, Blasticidin) 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)
