PP2B-B1 CRISPR/Cas9 KO Plasmid (m): sc-422386
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- PP2B-B1 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 PP2B-B1 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: PP2B-B1 Antibody (70-A): sc-130393

Overview
Ppp3r1 encodes the PP2B regulatory subunit B1 (calcineurin B1), an essential Ca2+-binding partner that stabilizes and modulates calcineurin phosphatase activity. Through Ca2+/calmodulin-dependent signaling, calcineurin controls dephosphorylation of substrates such as NFAT transcription factors, linking calcium flux to transcriptional programs that govern immune activation, neuronal plasticity, and muscle remodeling. In mouse models, PPP3R1-dependent signaling intersects with pathways regulating T cell receptor responses, synaptic function, and cardiac hypertrophy-associated remodeling, making it relevant to studies of inflammation, neurobiology, and stress-adaptive signaling. Dysregulated calcineurin activity is broadly implicated in pathological remodeling and immune dysfunction, positioning PP2B-B1 as a mechanistic node for pathway dissection in disease-relevant systems.
PP2B-B1 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Ppp3r1 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Ppp3r1 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 Ppp3r1 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 PP2B-B1 protein expression.
This CRISPR knockout system enables efficient generation of Ppp3r1-deficient cell models for investigation of PP2B-B1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by PP2B-B1 CRISPR/Cas9 KO Plasmid (m) and PP2B-B1 CRISPR/Cas9 KO Plasmid (m2) target distinct sites within the Ppp3r1 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by PP2B-B1 HDR Plasmid (m) and PP2B-B1 HDR Plasmid (m2) contain a puromycin resistance cassette and an RFP reporter flanked by Ppp3r1 homology arms to support homology-directed repair at defined Ppp3r1 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
