beta Actin Double Nickase Plasmid (m): sc-418965-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- beta Actin Double Nickase Plasmid (m) consists of a pair of plasmids each encoding a D10A mutated Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed to knockout gene expression with greater specificity than its CRISPR/Cas9 KO counterpart
- Paired gRNA sequences are offset by approximately 20 bp to allow for specific Cas9-mediated double nicking of the genomic DNA, which mimics a DSB
- One plasmid in the pair contains a puromycin-resistance gene for selection; the other plasmid in the pair contains a GFP marker to visually confirm transfection
- beta Actin Double Nickase Plasmid (m) and beta Actin Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Actb. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: beta Actin Antibody (C4): sc-47778

Mouse Actb encodes beta Actin, a highly conserved cytoskeletal protein that polymerizes into filamentous actin to support cell shape, cortical tension, and intracellular transport. Actin dynamics coordinate fundamental processes including cell migration, adhesion, cytokinesis, and mechanotransduction through pathways involving Rho-family GTPases, integrin signaling, and actin-binding regulators such as the Arp2/3 complex and cofilin. Perturbation of actin remodeling impacts tissue development and homeostasis and is broadly relevant to disease-associated phenotypes involving altered cell motility, barrier function, and cytoskeletal integrity. As a central node in cytoskeletal networks, Actb is frequently used to interrogate structure–function relationships and to normalize or benchmark cellular perturbations in mouse model systems.
beta Actin Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Actb locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Actb. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Actb function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Actb-disrupted clones.
