Laminin α-3 Double Nickase Plasmid (h): sc-401849-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Laminin α-3 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
- Laminin α-3 Double Nickase Plasmid (h) and Laminin α-3 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting LAMA3. One or both designs may be available

LAMA3 encodes the laminin α3 chain, a core component of laminin-332 in basement membranes that supports epithelial adhesion, polarity, and tissue architecture. Laminin α3 engages integrins such as α3β1 and α6β4 to regulate hemidesmosome assembly, focal adhesion signaling, and downstream pathways including FAK/Src, PI3K–AKT, and MAPK that coordinate migration and survival. Through its role in extracellular matrix organization and cell–matrix communication, LAMA3 influences wound re-epithelialization, barrier integrity, and epithelial differentiation programs. Altered laminin-332 composition or LAMA3 dysregulation is studied in contexts involving epidermal fragility phenotypes, impaired adhesion, and tumor cell invasion within epithelial-derived malignancies.
Laminin α-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the LAMA3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within LAMA3. 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 LAMA3 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 LAMA3-disrupted clones.
