Members such as FOXO1, FOXO3, FOXA2, and FOXP1 regulate diverse processes including cell cycle progression, apoptosis, metabolism, oxidative stress resistance, and development. FOXO factors in particular act downstream of the PI3K\/AKT pathway: AKT-mediated phosphorylation drives their nuclear exclusion, while loss of growth factor signaling permits nuclear accumulation and activation of target genes. Forkhead transcription factors are central to aging, immune regulation, and stem cell maintenance, and their dysregulation is implicated in cancer and metabolic disease, making FKH activity a valuable research readout.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Description \u0026amp; Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe FKH Reporter Lentivirus places a reporter gene under the control of tandem forkhead response elements, providing a sensitive readout of forkhead transcription factor DNA-binding activity in human and mouse cells. It detects the activity of factors that bind FKH elements, including FOXO1, FOXO3, FOXA2, and FOXP1. Reporter options include fluorescent (GFP, RFP, EGFP, mCherry) and luminescent (firefly and Renilla luciferase) formats, with blasticidin or puromycin selection.\u003c\/p\u003e\n\u003cp\u003eThe 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 FOXO and PI3K\/AKT pathway activity, studying metabolism and stress responses, and screening modulators of forkhead transcription factors.\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 reporter gene under the control of tandem consensus response elements specific for the Forkhead (FKH) Transcription Factors 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":53251616735597,"sku":"LTV-0039-1S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6","offer_id":53310901223789,"sku":"LTV-0039-2S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Puromycin \/ 2x10^6","offer_id":53310901256557,"sku":"LTV-0039-3S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Firefly Luc \/ Blasticidin \/ 2x10^6","offer_id":53310901289325,"sku":"LTV-0039-4S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Blasticidin \/ 5x10^6","offer_id":53310901322093,"sku":"LTV-0039-5S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Puromycin \/ 5x10^6","offer_id":53310901354861,"sku":"LTV-0039-6S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"Renilla Luc \/ Blasticidin \/ 2x10^6","offer_id":53310901387629,"sku":"LTV-0039-4SIC","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/LTV-0039-FKH-Reporter-Fig-2.jpg?v=1776934391","url":"https:\/\/www.ebiohippo.com\/products\/fkh-reporter-lentivirus-bhv19400035","provider":"BioHippo","version":"1.0","type":"link"}
