Produced largely by the liver under growth hormone control, and also locally in many tissues, IGF1 acts through the IGF1 receptor tyrosine kinase to activate the PI3K-AKT and RAS-MAPK pathways. This signaling promotes cell proliferation, growth, survival, and differentiation, and IGF1 is a central mediator of postnatal somatic growth and tissue regeneration. Dysregulated IGF1 signaling is associated with growth disorders, metabolic disease, and cancer progression, making IGF1 an important target in endocrinology, metabolism, and oncology research.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Description \u0026amp; Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe Human IGF1 shRNA Lentivirus delivers a validated short hairpin RNA that achieves at least 70% knockdown of human insulin-like growth factor 1 (IGF1). The shRNA is expressed from a U6 promoter in a third-generation, self-inactivating lentiviral backbone, with a co-expressed fluorescent reporter (GFP or RFP, optionally with luciferase) and antibiotic selection marker for stable cell line generation. Knockdown is confirmed using a rapid fluorescence-based assay. The shRNA lentivirus set provides particles from a mix of two independent validated shRNAs plus a matched scrambled control. Applications include loss-of-function studies of IGF1 signaling in cell growth, proliferation, metabolism, and tumor biology. Particles are ultra-purified and concentrated to high titer by PEG precipitation and sucrose gradient centrifugation, transducing difficult-to-transfect cells, including primary and thawed cultures.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAbout This Product\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis validated shRNA lentivirus targeting IGF1 (NCBI Accession: NM_001111283) delivers a 19–20 bp shRNA from a third-generation, self-inactivating lentiviral backbone. Expression is driven from a U6 Pol III promoter, with a constitutively expressed fluorescent reporter (GFP, GFP\/Luc, RFP, RFP\/Luc) and antibiotic selection marker (Blasticidin, Puromycin) co-expressed from the same vector. VSV-G pseudotyping enables broad cell tropism, including primary, suspension, and cryopreserved cell types.\u003c\/p\u003e\n\u003cp\u003eKnockdown is validated using a proprietary bicistronic fluorescence assay in which the target mRNA is co-expressed fused to RFP alongside the shRNA-GFP construct. At least 70% reduction in RFP signal in GFP-positive cells confirms on-target activity — a more direct functional readout than transcript-level qPCR. Polyclonal stable lines can be generated by antibiotic selection within 10 days, preserving parental cell heterogeneity compared to single-clone CRISPR approaches.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"LipExoGen Biotech","offers":[{"title":"GFP \/ Puromycin \/ 5x10^6 (sh-mix) + 5x10^6 (scr-mix)","offer_id":53251615523181,"sku":"LSV-0019-SET1","price":1195.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6 (sh-mix) + 5x10^6 (scr-mix)","offer_id":53311254430061,"sku":"LSV-0019-SET2","price":1195.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Puromycin \/ 5x10^6","offer_id":53311254462829,"sku":"LSV-0019-1S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6","offer_id":53311254495597,"sku":"LSV-0019-2S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP\/Luc \/ None \/ 2x10^6","offer_id":53311254528365,"sku":"LSV-0019-3S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP\/Luc \/ None \/ 2x10^6","offer_id":53311254561133,"sku":"LSV-0019-4S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Blasticidin \/ 5x10^6","offer_id":53311254593901,"sku":"LSV-0019-5S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Puromycin \/ 5x10^6","offer_id":53311254626669,"sku":"LSV-0019-6S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"None \/ Puromycin \/ 5x10^6","offer_id":53311254659437,"sku":"LSV-0019-7S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"None \/ Blasticidin \/ 5x10^6","offer_id":53311254692205,"sku":"LSV-0019-8S","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/LSV-0019-h-IGF1-sh-Fig1.jpg?v=1776934142","url":"https:\/\/www.ebiohippo.com\/products\/human-igf1-shrna-lentivirus-bhv19400134","provider":"BioHippo","version":"1.0","type":"link"}
