When AKT is inactive, FOXO3 enters the nucleus and binds Forkhead response elements to activate genes controlling cell cycle arrest, apoptosis, DNA repair, oxidative stress resistance, and metabolism. FOXO3 contributes to stem cell maintenance, longevity, and tumor suppression, and its activity is opposed by growth factor signaling. FOXO3 is widely studied in aging, cell survival, and cancer research, and shares features with the related factor FOXO1.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Description \u0026amp; Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe FOXO3 Reporter Lentivirus is a transcription factor reporter system that places a reporter gene under the control of tandem consensus response elements coupled to a minimal promoter, giving a sensitive fluorescent or luminescent readout of FOXO3 activity. The reporter is preferentially activated by FOXO3 rather than FOXO1 and can also read out transcriptional inhibition by FOXP1. Reporter options include EGFP, GFP, mCherry, RFP, firefly luciferase, Renilla luciferase, and a β-Lactamase-V5 reporter, with optional blasticidin or puromycin selection. Particles are purified by PEG precipitation and sucrose gradient centrifugation and efficiently transduce difficult-to-transfect cells, including primary and thawed cells.\u003c\/p\u003e\n\u003cp\u003eIt supports stable reporter cell line generation for studying FOXO3 signaling in cell survival and stress responses.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAbout This Product\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis reporter lentivirus places a EGFP, Firefly Luc, GFP, Luc, mCherry, Renilla Luc, RFP, β-Lactamase-V5 reporter gene under the control of tandem consensus response elements specific for the FOXO3 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":53251617816941,"sku":"LTV-0041-1S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6","offer_id":53310904729965,"sku":"LTV-0041-2S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Puromycin \/ 2x10^6","offer_id":53310904762733,"sku":"LTV-0041-3S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Blasticidin \/ 2x10^6","offer_id":53310904795501,"sku":"LTV-0041-4S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Blasticidin \/ 5x10^6","offer_id":53310904828269,"sku":"LTV-0041-5S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Puromycin \/ 5x10^6","offer_id":53310904861037,"sku":"LTV-0041-6S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Renilla Luc \/ Blasticidin \/ 2x10^6","offer_id":53310904893805,"sku":"LTV-0041-4SIC","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/LTV-0041-FOXO3-Reporter-Fig.jpg?v=1776934450","url":"https:\/\/www.ebiohippo.com\/products\/foxo3-reporter-lentivirus-bhv19400037","provider":"BioHippo","version":"1.0","type":"link"}
