SMO/Smoothened Double Nickase Plasmid (h): sc-400491-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- SMO/Smoothened 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
- SMO/Smoothened Double Nickase Plasmid (h) and SMO/Smoothened Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting SMO. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: SMO/Smoothened Antibody (E-5): sc-166685

SMO (Smoothened) is a seven-transmembrane signal transducer that functions downstream of PTCH1 in the Hedgehog pathway to regulate GLI-dependent transcriptional programs controlling embryonic patterning, stem and progenitor cell maintenance, and tissue homeostasis. In the absence of Hedgehog ligands, PTCH1 restrains SMO activity; ligand binding relieves this inhibition, enabling SMO accumulation and signaling from the primary cilium. Dysregulated SMO signaling perturbs developmental gene expression and has been linked to oncogenic pathway activation and aberrant cell fate decisions in multiple disease contexts. Human SMO is therefore widely studied for pathway mapping, ciliary signaling biology, and transcriptional network regulation.
SMO/Smoothened Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SMO locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SMO. 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 SMO 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 SMO-disrupted clones.
