Background
Activating transcription factor 6 (ATF6) is an ER membrane-bound bZIP transcription factor and one of the three main sensors of the unfolded protein response. When unfolded proteins accumulate in the endoplasmic reticulum, ATF6 traffics to the Golgi, where it is cleaved to release an active nuclear fragment. This fragment binds ER stress-response elements to induce ER chaperones and folding enzymes such as GRP78, as well as transcription factors including XBP1. The ATF6 DNA-binding sequence is related to but distinct from ATF1/CREB elements. ATF6 signaling is essential for adapting to ER stress and is implicated in cancer, metabolic disease, and protein-misfolding disorders.
Product Description & Applications
The ATF6 Reporter Lentivirus is a transcription factor reporter system built with tandem repeats of consensus ATF6 DNA-binding elements upstream of a minimal promoter and a reporter gene, giving a sensitive fluorescent or luminescent readout of ATF6 transcriptional activity. The element responds specifically to active ATF6 and is strongly induced by ER stress stimuli such as tunicamycin. A wide range of reporters is available, including EGFP, mCherry, BFP2, d2GFP, firefly luciferase, Gaussia luciferase, and Renilla luciferase, with selection markers including blasticidin, hygromycin, puromycin, and zeocin. Particles are purified by PEG precipitation and sucrose gradient centrifugation and efficiently transduce difficult-to-transfect cells.
It supports stable reporter cell line generation for studying ER stress and the unfolded protein response.
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 ATF6 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.

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)
