MARE Reporter Lentivirus: High-quality, lentiviral transcription factor (TF) reporter system that provides a sensitive fluorescent or luminescent readout for human/mouse MAF bZIP transcription factors (MAFs). The construct utilizes tandem repeats of MAF response elements (T-MARE) upstream of a fluorescent or luminescent reporter readout transcriptional activity of MAF TFs, such as MAF-C, MAF-B, and MAF-L, in mammalian cells. The reporter lentivirus is purified by PEG precipitation and sucrose gradient centrifugation, and is ideal for studying transcriptional activity of MAFs in difficult-to-transfect cells including primary and/or thawed cells.

| Monitor transcriptional activity of MAFs (e.g. MAF-B, MAF-C, MAF-L) in mammalian cells, screen for activators or inhibitors of MAFs signaling. The fluorescent reporter enables convenient readout using flow cytometry, fluorescence microscopy, etc. MAFs contribute to the formation of lens cytoskeletal structure. Both MAF-C (c-MAF) and MAF-B are transcriptional activators, although MAF-B is less potent than MAF-C. MAF-C is a bona fide oncogene contributing to the progression of hematological malignancies and is overexpressed in other cancers, such as renal and head and neck cancer. MAF-B plays a pivotal role in regulating lineage-specific hematopoiesis by repressing ETS1-mediated transcription of erythroid-specific genes in myeloid cells, and is required for monocytic, macrophage, osteoclast, podocyte and islet beta cell differentiation. MAF-B also activates the insulin and glucagon promoters. The MARE reporter utilizes tandem repeats of T-MARE to read out transcriptional activity of MAFs in mammalian cells. | |

Product Data
Figure 1 (thumbnail). GFP reporter activation in cells co-transfected with MARE-TAG-Puro reporter and MAF-B expression vector. HEK293FT cells were co-transfected with MARE-TAG-Puro plasmid along with empty vector (pcDNA) or an expression vector for human MAF-B with an RFP reporter separated by P2A. After 24-36 h, images were acquired by fluorescence microscopy. GFP indicates the reporter activation in response to MAF-B. This product is supplied as pre-packaged lentiviral particles with your choice of reporter and selection marker. MAF-B cDNA expression vector is also available upon request.

Recommended Controls
Reporter Negative Control Lentivirus – Ready-to-transduce lentiviral particles expressing minimal TATA box-driven reporter. The construct is the same as the TF Reporters except that it lacks the transcriptional response elements which drive signal pathway/TF-specific reporter expression. The reporter negative control lentiviral particles allow to establish a baseline for background reporter activity and determine specificity of any treatments to activate the reporter.
Reporter Positive Control Lentivirus – Ready-to-transduce lentiviral particles with constitutive expression of the reporter. The reporter positive control lentivirus is useful for transduction optimization studies, especially if the cells are very sensitive or difficult-to-transduce.
Renilla Luciferase Internal Control Lentivirus – Ready-to-transduce lentiviral particles expressing minimal TATA box-driven Renilla luciferase (RLuc).

Additional Information
Additional Information
- High Sensitivity – LipExoGen FOXO3 Reporter lentiviral particles are made using a novel vector platform based on the third generation system. Transcriptional response elements which are preferentially recognized by FOXO3 are arranged as DNA tandem repeats upstream of the minimal TATA promoter-driven reporter, and downstream of an optimized minimal enhancer (pc) of the human CMV promoter. When the signal pathway/TF is activated, the mini enhancer synergizes with TF binding to the response elements (up to 8 repeats in some products, depending on strength of reporter activation) to amplify expression of the fluorescent (GFP/RFP) or luciferase (Luc) reporter, with minimal enhancement of background. As a result, the reporter system provides a highly sensitive readout for signaling pathway or specific transcription factor activation in human and mouse cells.
- Easily Establish Stable Reporter Cell Lines – The reporter lentiviral particles are ultra-purified and concentrated to high-titer by PEG purification and sucrose gradient centrifugation to allow for efficient transduction of difficult-to-transfect cells, including primary and/or freeze-thawed cells. Stable cell lines are easily generated through puromycin or blasticidin selection.
- Discovery Made Easy – Signal pathway or specific transcription factor activity can be detected by fluorescence, making LipExoGen TF Reporter lentiviral particles more practical than traditional luciferase reporters and/or biochemical assays. Pathway/TF activation can be readout directly by fluorescence microscopy in living cell cultures, thus paving the way for unexpected discoveries.
- Readout On Flow – Fluorescent reporter activation can also be readout by flow cytometry, providing more versatility in data acquisition for labs with different instruments.
- Best Value – LipExoGen lentiviral particle products are made using optimized lentiviral vectors developed in-house, which allows us to provide the highest quality products while retaining competitive prices. These high-titer lentiviral particles feature a highly sensitive fluorescent reporter system which has been validated to read out the activity of the indicated transcription factor or signaling pathway.
- Same Cost For Custom Lentivirus – You can easily request any combination of reporter (GFP/RFP/Luc) and selection marker (puromycin/blasticidin) for this product, without additional cost, by contacting us. To view our complete list of vectors, click here.
