Background
PDGFD encodes platelet-derived growth factor D, a member of the PDGF family of growth factors. PDGF-D is secreted as a latent dimer that is proteolytically activated and signals primarily through the PDGF receptor beta to drive proliferation, migration, and survival of mesenchymal cells, including fibroblasts and vascular smooth muscle cells. PDGF-D signaling contributes to angiogenesis, tissue remodeling, and fibrosis. Elevated PDGF-D expression promotes tumor growth, epithelial-mesenchymal transition, and metastasis in several cancers, making it a target of interest in cancer and cell biology research.
Product Description & Applications
The Human PDGFD shRNA Lentivirus delivers a validated short hairpin RNA targeting human PDGFD 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.
A shRNA set option supplies a mix of two validated shRNAs plus a scrambled control for loss-of-function studies of PDGF-D signaling and tumor biology.
About This Product
This validated shRNA lentivirus targeting PDGFD (NCBI Accession: NM_025208) 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)
