PDGF Receptor alpha/PDGFRA CRISPR/Cas9 KO Plasmid (h2): sc-400107-KO-2
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- PDGF Receptor alpha/PDGFRA CRISPR/Cas9 Knockout (KO) Plasmid (h2) is a pool of plasmids, each encoding Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed for maximum knockout efficiency using sequences derived from the GeCKO v2 library
- gRNA sequences direct Cas9 to induce site-specific double-strand breaks (DSBs) in the PDGF Receptor alpha/PDGFRA genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- PDGF Receptor alpha/PDGFRA HDR Plasmid (h2) (sc-400107-HDR-2) is recommended for co-transfection with PDGF Receptor alpha/PDGFRA CRISPR/Cas9 KO Plasmid (h2) to enable selection of successfully edited cells through HDR-mediated integration of a puromycin resistance cassette and RFP reporter gene
- PDGF Receptor alpha/PDGFRA HDR Plasmid (h2) is a pool of plasmids, each containing a homology-directed repair (HDR) template corresponding to the gRNA target sites in the PDGF Receptor alpha/PDGFRA CRISPR/Cas9 KO Plasmid (h2)
- Each HDR plasmid contains two ~800 bp homology arms flanking the puromycin resistance and RFP cassettes, designed to bind genomic DNA sequences surrounding the Cas9-induced double-strand break site and facilitate precise HDR-mediated integration
- The puromycin resistance and RFP genes are flanked by LoxP sites, enabling removal of selection markers via Cre recombinase (Cre Vector: sc-418923) after establishing stable knockout cell lines
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: PDGF Receptor alpha/PDGFRA Antibody (C-9): sc-398206

Overview
PDGFRA encodes platelet-derived growth factor receptor alpha (PDGFRα), a receptor tyrosine kinase activated by PDGF ligands that initiates autophosphorylation and downstream signaling through MAPK/ERK, PI3K/AKT, and PLCγ pathways. PDGFRα regulates cell proliferation, survival, chemotaxis, and differentiation, with prominent roles in mesenchymal lineage biology, stromal cell function, and tissue development. Aberrant PDGFRA signaling caused by mutation, amplification, or fusion events is linked to dysregulated growth control and altered tumor microenvironment interactions in multiple malignancies, and it is also implicated in fibrotic and proliferative disorders. As a cell-surface signaling node, PDGFRα is frequently used to interrogate receptor-mediated signaling dynamics, ligand specificity, and pathway crosstalk in human cell models.
PDGF Receptor alpha/PDGFRA CRISPR/Cas9 KO Plasmid (h2) is a pool of plasmids designed for targeted disruption of the PDGFRA gene in human cell lines. Each plasmid in the pool co-expresses a unique sgRNA, targeting a distinct site within the PDGFRA locus, alongside the Streptococcus pyogenes Cas9 nuclease, and encodes GFP to enable fluorescent identification and enrichment of successfully transfected cells. This multi-guide strategy increases the likelihood of inducing frameshifts or deletions that produce a functional knockout, offering a more robust alternative to single-guide approaches. DSBs induced at multiple sites are resolved through non-homologous end joining (NHEJ) or, when used with the included HDR donor template, homology-directed repair (HDR) at a defined target site within the locus.
When used in conjunction with the RFP-expressing HDR donor, GFP and RFP fluorescence can be used together to distinguish transfected from edited cell populations, streamlining flow cytometry-based sorting and clone selection workflows.
Homology-Directed Repair (HDR) Donor — Puromycin Cassette with RFP Reporter
For applications requiring confirmed, selectable knockout clones, PDGF Receptor alpha/PDGFRA HDR Plasmid (h2) includes an HDR donor construct containing a puromycin resistance cassette (PuroR) and a red fluorescent protein (RFP) reporter, flanked by homology arms specific to a defined PDGFRA target site.
When co-transfected with PDGF Receptor alpha/PDGFRA CRISPR/Cas9 KO Plasmid (h2):
- The PuroR-RFP cassette integrates at the Cas9 cut site via HDR, disrupting the PDGFRA open reading frame.
- RFP fluorescence provides an immediate visual indicator of successful integration, enabling fluorescence-based identification or sorting of edited cells prior to or alongside puromycin selection.
- Successfully edited cells are confirmed through puromycin resistance, substantially reducing clone screening burden.
- This selection strategy is ideal for generating stable, clonal KO cell lines for downstream functional studies, drug screening, or model development.
Cre-lox Cassette Removal System
The HDR donor construct features loxP sites flanking the PuroR-RFP selection cassette to allow clean marker removal following clone confirmation. Transient expression of Cre recombinase via the included Cre Vector: sc-418923 excises the cassette, leaving a minimal residual loxP site within the PDGFRA locus and eliminating potential confounding effects on downstream assays.
This two-step approach:
- Minimizes disruption to local chromatin architecture and neighboring regulatory elements
- Restores a near-native genomic context at the edited locus
- Enables reuse of the puromycin selection strategy in the same cell line for additional edits
