In the liver it directs a large fraction of hepatic genes, including HNF1α and genes governing gluconeogenesis and lipid metabolism. HNF4α is also active in the pancreas, where it controls islet gene programs, and in the intestine, where it regulates lipid metabolism and energy expenditure. Pathogenic HNF4α mutations cause maturity-onset diabetes of the young (MODY1), and loss-of-function variants are linked to hyperinsulinemic hypoglycemia, underscoring its importance in metabolism and diabetes research.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Description \u0026amp; Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe HNF4α Reporter Lentivirus is a transcription-factor reporter system for sensitive fluorescent or luminescent detection of human and mouse HNF4α activity. It contains tandem repeats of consensus HNF4α DNA-binding elements, coupled to a minimal TATA-box promoter and an upstream enhancer that maximizes signal-to-noise to drive a reporter gene (d2GFP, EGFP, GFP, mCherry, RFP, or firefly luciferase). A constitutively expressed selection marker (puromycin or blasticidin) supports stable polyclonal cell line generation. Stable lentiviral integration provides consistent reporter expression in dividing and post-mitotic cells, including primary and cryopreserved material, with readout by microscopy, flow cytometry, or luminometry. It is used to study HNF4α transcriptional activity in metabolism and diabetes research. Supplied as purified lentiviral particles.\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 HNF4a transcription factor, coupled to a minimal TATA-box promoter and a proprietary upstream enhancer that maximizes signal-to-noise. The constitutively expressed selection marker (Puromycin, Blasticidin) 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":53251620077933,"sku":"LTV-0080-1S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6","offer_id":53362030477677,"sku":"LTV-0080-2S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Puromycin \/ 2x10^6","offer_id":53362030510445,"sku":"LTV-0080-3S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Blasticidin \/ 2x10^6","offer_id":53362030543213,"sku":"LTV-0080-4S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Blasticidin \/ 5x10^6","offer_id":53362030575981,"sku":"LTV-0080-5S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Puromycin \/ 5x10^6","offer_id":53362030608749,"sku":"LTV-0080-6S","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/HNF4alpha-Fig.-2.jpg?v=1776934389","url":"https:\/\/www.ebiohippo.com\/products\/hnf4-alpha-reporter-lentivirus-bhv19400212","provider":"BioHippo","version":"1.0","type":"link"}
