RCAN3 CRISPR/Cas9 KO Plasmid (m): sc-424773
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- RCAN3 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 RCAN3 genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- RCAN3 HDR Plasmid (m) (sc-424773-HDR) is recommended for co-transfection with RCAN3 CRISPR/Cas9 KO Plasmid (m) to enable selection of successfully edited cells through HDR-mediated integration of a puromycin resistance cassette and RFP reporter gene
- RCAN3 HDR Plasmid (m) is a pool of plasmids, each containing a homology-directed repair (HDR) template corresponding to the gRNA target sites in the RCAN3 CRISPR/Cas9 KO Plasmid (m)
- 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

Overview
Rcan3 encodes RCAN3, a member of the regulators of calcineurin (RCAN) family that modulates the calcium/calmodulin-dependent phosphatase calcineurin and downstream NFAT transcriptional programs. By tuning calcineurin–NFAT signaling, RCAN3 influences calcium-dependent gene expression linked to immune activation, muscle and neuronal physiology, and cellular adaptation to stress. RCAN3 has also been connected to regulation of phosphorylation-dependent signaling and transcriptional responses that shape cell growth and differentiation. Dysregulated calcineurin/NFAT activity is relevant to inflammatory processes, cardiac remodeling, and neuromuscular phenotypes, making Rcan3 a useful target for pathway-focused functional genomics in mouse systems.
RCAN3 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Rcan3 gene in mouse cell lines. Each plasmid in the pool co-expresses a unique sgRNA, targeting a distinct site within the Rcan3 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, RCAN3 HDR Plasmid (m) 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 Rcan3 target site.
When co-transfected with RCAN3 CRISPR/Cas9 KO Plasmid (m):
- The PuroR-RFP cassette integrates at the Cas9 cut site via HDR, disrupting the Rcan3 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 Rcan3 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
