Background
HOXA9 is a homeodomain-containing transcription factor that plays a critical role in hematopoietic stem and progenitor cell expansion and differentiation. It regulates gene transcription by binding promoter-distal enhancers, frequently in cooperation with cofactors such as MEIS1 and PBX proteins, and influences the expression of genes governing proliferation and self-renewal. HOXA9 expression is normally downregulated during myeloid maturation, but it is frequently deregulated in acute leukemias. In acute myeloid leukemia, diverse upstream genetic alterations converge on HOXA9 overexpression, contributing to a block in differentiation and oncogenic transformation. These roles make HOXA9 an important target in leukemia and hematopoiesis research.
Product Description & Applications
The HOXA9 Reporter Lentivirus places a reporter gene under the control of tandem consensus HOXA9 DNA-binding elements, providing a sensitive readout of HOXA9 transcriptional activity in human and mouse cells. Reporter options include fluorescent (GFP, EGFP, d2GFP, mCherry, RFP) and luminescent (firefly luciferase) formats, with blasticidin or puromycin selection for stable reporter cell line establishment. Detection is possible by fluorescence microscopy, flow cytometry, or luminometry.
The particles are purified by PEG precipitation and sucrose gradient centrifugation and efficiently transduce difficult-to-transfect cells, including primary and cryopreserved cultures. Applications include monitoring HOXA9 activity in hematopoietic and leukemia models and screening modulators of HOXA9-driven transcription.
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 HOXA9 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)
