These factors bind MARE sequences as homodimers or as heterodimers with other bZIP proteins to regulate cell-type-specific gene expression. Large MAF proteins are important for terminal differentiation of multiple lineages, contributing to processes such as lens development, pancreatic beta cell function, and macrophage and immune cell differentiation. Dysregulated MAF expression is associated with certain cancers, including multiple myeloma. MAF transcription factors are therefore relevant to studies of differentiation, development, and disease.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Description \u0026amp; Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe MARE Reporter Lentivirus is a transcription factor reporter system that provides a sensitive fluorescent or luminescent readout of MAF bZIP transcription factor activity in human or mouse cells. The construct uses tandem repeats of MAF response elements (T-MARE) upstream of a fluorescent (GFP, RFP, EGFP, d2GFP, mCherry) or luminescent (firefly luciferase) reporter, enabling detection of transcriptional activity of MAF family factors such as c-MAF, MAFB, and related proteins. Antibiotic selection markers (puromycin or blasticidin) support establishment of stable reporter cell lines. The system is used to study MAF-driven transcription, cell differentiation, and the signaling that regulates MAF activity. Supplied as lentiviral particles purified by PEG precipitation and sucrose gradient centrifugation, it efficiently transduces difficult-to-transfect cells, including primary and thawed cells.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAbout This Product\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis reporter lentivirus places a d2GFP, EGFP, Firefly Luc, GFP, mCherry, RFP reporter gene under the control of tandem consensus response elements specific for the MAF Signaling Pathway 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.\u003c\/p\u003e\n\u003cp\u003eStable 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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"LipExoGen Biotech","offers":[{"title":"GFP \/ Puromycin \/ 5x10^6","offer_id":53251619717485,"sku":"LTV-0067-1S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6","offer_id":53310901780845,"sku":"LTV-0067-2S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Puromycin \/ 2x10^6","offer_id":53310901813613,"sku":"LTV-0067-3S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Blasticidin \/ 2x10^6","offer_id":53310901846381,"sku":"LTV-0067-4S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Blasticidin \/ 5x10^6","offer_id":53310901879149,"sku":"LTV-0067-5S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Puromycin \/ 5x10^6","offer_id":53310901911917,"sku":"LTV-0067-6S","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/TF-Reporter-Vector-circular_8145a26f-a65c-499b-8548-059383fb14dd.jpg?v=1776934330","url":"https:\/\/www.ebiohippo.com\/products\/mare-reporter-lentivirus-bhv19400062","provider":"BioHippo","version":"1.0","type":"link"}
