PI 3-kinase p110β Double Nickase Plasmid (m): sc-428980-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- PI 3-kinase p110β 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
- PI 3-kinase p110β Double Nickase Plasmid (m) and PI 3-kinase p110β Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Pik3cb. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: PI 3-kinase p110β Antibody (C-8): sc-376641

Pik3cb encodes the class IA phosphoinositide 3-kinase catalytic subunit p110β, a lipid kinase that phosphorylates PIP2 to generate PIP3 and propagate PI3K–AKT signaling. In mouse cells, p110β contributes to growth factor receptor and GPCR-linked signaling, coordinating downstream processes such as cell survival, proliferation, metabolism, vesicular trafficking, and cytoskeletal dynamics. It functions in concert with regulatory p85 subunits to control pathway amplitude and spatial signaling. Dysregulation of PI3K pathway components, including altered p110β activity, is widely studied in contexts of aberrant cell growth, metabolic phenotypes, and immune-related signaling defects.
PI 3-kinase p110β Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Pik3cb locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Pik3cb. 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 Pik3cb 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 Pik3cb-disrupted clones.
