Ligand binding triggers receptor dimerization and autophosphorylation, activating downstream RAS\/MAPK, PI3K\/AKT, and STAT signaling cascades that control cell proliferation, survival, migration, and differentiation. EGFR is a well-established oncogene: amplification, overexpression, and activating mutations drive many epithelial cancers, including lung, colorectal, and head and neck tumors. EGFR is one of the most prominent targets of cancer therapy, with both antibody and small-molecule inhibitors in clinical use, making it a central focus of cancer and cell biology research.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Description \u0026amp; Applications\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe h\/m EGFR shRNA Lentivirus delivers a validated short hairpin RNA targeting human and mouse EGFR for stable RNA interference. 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 optional blasticidin or puromycin selection. Particles are ultra-purified and concentrated by PEG precipitation and sucrose gradient centrifugation and efficiently transduce difficult-to-transfect cells, including primary and thawed cells. The shRNA is validated for at least 70% knockdown using a fluorescence-based assay.\u003c\/p\u003e\n\u003cp\u003eA shRNA set option supplies a mix of two validated shRNAs plus a scrambled control for loss-of-function studies of EGFR signaling and tumor cell biology.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAbout This Product\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis validated shRNA lentivirus targeting EGFR (NCBI Accession: NM_005228.5) 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":53251619520877,"sku":"LSV-0051-SET1","price":1195.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6 (sh-mix) + 5x10^6 (scr-mix)","offer_id":53311267176813,"sku":"LSV-0051-SET2","price":1195.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Puromycin \/ 5x10^6","offer_id":53311267209581,"sku":"LSV-0051-1S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Blasticidin \/ 5x10^6","offer_id":53311267242349,"sku":"LSV-0051-2S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP\/Luc \/ None \/ 2x10^6","offer_id":53311267275117,"sku":"LSV-0051-3S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP\/Luc \/ None \/ 2x10^6","offer_id":53311267307885,"sku":"LSV-0051-4S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"GFP \/ Blasticidin \/ 5x10^6","offer_id":53311267340653,"sku":"LSV-0051-5S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"RFP \/ Puromycin \/ 5x10^6","offer_id":53311267373421,"sku":"LSV-0051-6S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"None \/ Puromycin \/ 5x10^6","offer_id":53311267406189,"sku":"LSV-0051-7S","price":595.0,"currency_code":"USD","in_stock":true},{"title":"None \/ Blasticidin \/ 5x10^6","offer_id":53311267438957,"sku":"LSV-0051-8S","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/LSV-0051-hm-EGFR-9p-1.jpg?v=1776934150"},{"product_id":"trop2-lentivirus-macaca-fascicularis-cynomolgus-bhv18200015","title":"Trop2 Lentivirus (Macaca fascicularis\/Cynomolgus)","description":"\u003cstyle\u003e\n.bhp-desc{font-size:16px;color:#1a1a1a;line-height:1.7}\n.bhp-desc h2{font-size:18px;font-weight:700;color:#003366;margin:24px 0 10px;padding-bottom:6px;border-bottom:2px solid #003366}\n.bhp-desc p{margin:0 0 12px}\n.bhp-desc .bhp-spec-table{width:100%;border-collapse:collapse;margin:12px 0 18px}\n.bhp-desc .bhp-spec-table th{width:36%;text-align:left;padding:8px 12px;background:#e8f0fb;color:#003366;font-weight:600;vertical-align:top;border:1px solid #ccd9f0}\n.bhp-desc .bhp-spec-table td{padding:8px 12px;vertical-align:top;border:1px solid #ccd9f0}\n.bhp-desc .bhp-qc-badge{display:inline-block;background:#e6f4ea;color:#1a7a3c;border:1px solid #a8d5b5;border-radius:4px;padding:6px 14px;font-size:14px;font-weight:600}\n.bhp-desc .bhp-warning-box{background:#fff8e6;border-left:4px solid #e6a817;padding:10px 14px;margin:10px 0 14px;border-radius:0 4px 4px 0}\n.bhp-desc .bhp-license-box{background:#f5f5f5;border:1px solid #ddd;border-radius:4px;padding:12px 16px;font-size:14px;color:#444}\n.bhp-desc .bhp-cat-pill{display:inline-block;background:#003366;color:#fff;border-radius:20px;padding:3px 12px;font-size:13px;margin-bottom:10px}\n\u003c\/style\u003e\n\u003cdiv class=\"bhp-desc\"\u003e\n\u003ch2\u003eScientific Background\u003c\/h2\u003e\n\u003cp\u003eTrophoblast cell-surface antigen 2 (Trop-2, also known as tumor-associated calcium signal transducer 2, TACSTD2, GA733-1 or M1S1), is a cell surface glycoprotein involved in stem-cell like functions. It is overexpressed in a variety of solid cancers compared to normal cells, and links with patient prognosis. Through a variety of signaling pathways, Trop-2 regulates cancer growth and metastasis. The use of antibodies, antibody-fusion proteins, small molecule inhibitors and other strategies directed at Trop-2 has resulted in promising results.

Visit: bpsbioscience.com\/cell-line-faq for guidelines on performing a kill curve.  The lentiviruses are produced with a SIN (self-inactivation) lentivector which ensures self-inactivation of the lentiviral construct after transduction and after integration into the genomic DNA of the target cells. None of the HIV genes (gag, pol, rev) will be expressed in the transduced cells, as they are expressed from packaging plasmids lacking the packing signal and are not present in the lentivirus particle. Although the pseudotyped lentiviruses are replication-incompetent, they require the use of a Biosafety Level 2 facility. BPS Bioscience recommends following all local federal, state, and institutional regulations and using all appropriate safety precautions.
