Background
KRT10 encodes keratin 10, a type I intermediate filament protein expressed in differentiated, suprabasal keratinocytes of the epidermis. Keratin 10 pairs with the type II keratin 1 to form the intermediate filament network that provides mechanical strength and structural integrity to the upper layers of the skin. Its expression is a hallmark of keratinocyte terminal differentiation, and the keratin 1/keratin 10 network is essential for maintaining a functional epidermal barrier. Mutations in KRT10 cause epidermolytic ichthyosis, a skin disorder marked by blistering and abnormal keratinization. Keratin 10 is also studied as a differentiation marker in epithelial biology and in cancers arising from squamous epithelia.
Product Description & Applications
The h/m KRT10 shRNA Lentivirus delivers validated short hairpin RNA targeting human and mouse keratin 10 for stable gene knockdown. Each shRNA is validated to achieve at least 70% reduction of KRT10 using a fluorescence-based assay that provides a direct functional readout rather than transcript-level qPCR. The particles are ultra-purified and concentrated to high titer by PEG precipitation and sucrose gradient centrifugation, and efficiently transduce difficult-to-transfect cells, including primary and thawed cultures. A co-expressed fluorescent reporter (GFP or RFP, optionally with luciferase) and antibiotic selection marker (puromycin or blasticidin) enable stable line generation. A shRNA set option supplies a mix of two independent validated shRNAs plus matched scrambled-control lentivirus for loss-of-function studies of keratinocyte differentiation and epithelial biology.
About This Product
This validated shRNA lentivirus targeting KRT10 (NCBI Accession: NM_000421.5) 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, RFP, GFP/Luc, RFP/Luc) and antibiotic selection marker (Puromycin, Blasticidin) 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)
