GFRα-1 CRISPR/Cas9 KO Plasmid (m): sc-420539
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- GFRα-1 CRISPR/Cas9 Knockout (KO) Plasmid (m) 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 GFRα-1 genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- 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: GFRα-1 Antibody (E-11): sc-271546

Overview
Gfra1 encodes GFRα-1, a glycosylphosphatidylinositol-anchored co-receptor that binds glial cell line–derived neurotrophic factor (GDNF) and presents it to the RET tyrosine kinase to initiate downstream signaling. This ligand–receptor complex regulates neuronal survival, neurite outgrowth, and differentiation through pathways that include PI3K–AKT, MAPK/ERK, and PLCγ-dependent signaling, with additional roles in neural crest–derived tissues. In mouse, GFRα-1 activity is also implicated in kidney morphogenesis and the maintenance of spermatogonial stem cells, reflecting its broader function in developmental and tissue homeostasis programs. Dysregulation of GDNF–GFRα-1–RET signaling is widely used as a mechanistic framework for studying neurodevelopmental defects, neurodegeneration, and RET-driven cellular phenotypes in experimental models.
GFRα-1 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Gfra1 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Gfra1 together with the Streptococcus pyogenes Cas9 nuclease. The plasmids also encode GFP, allowing fluorescent identification and enrichment of successfully transfected cells by fluorescence microscopy or flow cytometry.
The multi-guide design increases the likelihood of generating insertions or deletions (indels) that disrupt the Gfra1 open reading frame following Cas9-mediated double-strand break formation. DNA breaks introduced by the CRISPR/Cas9 system are repaired through endogenous non-homologous end joining (NHEJ) pathways, frequently resulting in frameshift mutations that abolish GFRα-1 protein expression.
This CRISPR knockout system enables efficient generation of Gfra1-deficient cell models for investigation of GFRα-1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by GFRα-1 CRISPR/Cas9 KO Plasmid (m) and GFRα-1 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Gfra1 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by GFRα-1 HDR Plasmid (m) and GFRα-1 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Gfra1 homology arms to support homology-directed repair at defined Gfra1 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
