Background
KLF5 is a member of the Krüppel-like factor family of zinc-finger transcription factors. By binding GC-rich and CACCC DNA elements in target gene promoters, KLF5 regulates programs that control cell proliferation, differentiation, migration, and survival. It is highly expressed in proliferating epithelial cells and contributes to development and tissue homeostasis in the gut, skin, and other organs. KLF5 activity is tightly regulated by post-translational modification and protein turnover, and its dysregulation contributes to several cancers, where it can act as either an oncogene or tumor suppressor depending on context, making KLF5 an actively studied target in cancer and cell biology.
Product Description & Applications
The h/m KLF5 shRNA Lentivirus delivers a validated short hairpin RNA that achieves at least 70% knockdown of human and mouse KLF5. 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 KLF5 in cell proliferation, differentiation, epithelial biology, and cancer. 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.
About This Product
This validated shRNA lentivirus targeting KLF5 (NCBI Accession: NM_001730.5) 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.
Knockdown 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.

Common customization requests
- Insert / payload: replace the gene/sequence, swap to a different isoform, add mutations, or optimize cloning features.
- Expression design: change promoter (e.g., CMV/EF1α/PGK), add enhancers, or adjust regulatory elements.
- Reporters: add/swap GFP/RFP/mCherry/luciferase (single or dual reporters where applicable).
- Selection markers: add/swap puromycin/blasticidin/neomycin or fluorescent selection options.
- Vector format: switch between OE, shRNA, CRISPR (sgRNA/Cas systems), or control vectors (where supported).
Add-ons you can request
- Control viruses: empty vector, non-targeting shRNA, reporter-only controls, or matched backbone controls.
- Packaging / format: concentration options, aliquoting, or custom fill volume for screening workflows.
- Documentation: construct map/sequence confirmation package (as available) and batch documentation.
What to include in your request
- Target cell type/model (cell line or primary cells) and intended readout (reporter, knockdown, OE, etc.)
- Insert sequence (FASTA) or reference ID, plus any required tags/mutations
- Promoter, reporter, and selection marker preferences
- Desired scale and preferred format (aliquots / concentration requests)
