plexin-B2 CRISPR/Cas9 KO Plasmid (m): sc-431226
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- plexin-B2 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 plexin-B2 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: plexin-B2 Antibody (A-5): sc-373969

Overview
Plxnb2 encodes plexin-B2, a transmembrane receptor for class 4 semaphorins that integrates guidance cues with cytoskeletal remodeling and cell motility. Plexin-B2 signaling influences Rho family GTPase activity and interfaces with receptor tyrosine kinase pathways to coordinate adhesion, migration, and morphogenesis during neural development and tissue organization. In mouse systems, Plxnb2 function is frequently studied in axon guidance, epithelial branching, and regulation of cell–cell interactions within developing and adult tissues. Dysregulated semaphorin–plexin signaling has been linked to aberrant migration and invasion phenotypes in disease-relevant contexts, supporting its utility as a mechanistic node in pathways controlling tissue architecture.
plexin-B2 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Plxnb2 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Plxnb2 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 Plxnb2 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 plexin-B2 protein expression.
This CRISPR knockout system enables efficient generation of Plxnb2-deficient cell models for investigation of plexin-B2 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by plexin-B2 CRISPR/Cas9 KO Plasmid (m) and plexin-B2 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Plxnb2 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by plexin-B2 HDR Plasmid (m) and plexin-B2 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Plxnb2 homology arms to support homology-directed repair at defined Plxnb2 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
