4.1B Double Nickase Plasmid (h): sc-406853-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- 4.1B Double Nickase Plasmid (h) 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
- 4.1B Double Nickase Plasmid (h) and 4.1B Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting EPB41L3. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: 4.1B Antibody (B-6): sc-398089

EPB41L3 encodes protein 4.1B, a membrane-associated cytoskeletal adaptor that links the actin/spectrin network to transmembrane complexes to support cortical stability, cell polarity, and adhesion-dependent signaling. Through interactions at the plasma membrane and along cell–cell junctions, 4.1B contributes to cytoskeletal remodeling and membrane organization that influence motility and contact inhibition. Altered EPB41L3 expression or disruption of 4.1B-associated scaffolding has been associated with dysregulated migration and invasion phenotypes in multiple cancer contexts, supporting its use as a node for studying tumor suppressor-like pathways. As a human target, EPB41L3 is also relevant to investigations of epithelial integrity and signal transduction programs coupled to junctional architecture.
4.1B Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the EPB41L3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within EPB41L3. 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 EPB41L3 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 EPB41L3-disrupted clones.
