Desmuslin Double Nickase Plasmid (h): sc-409241-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Desmuslin 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
- Desmuslin Double Nickase Plasmid (h) and Desmuslin Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting SYNM. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Desmuslin Antibody (A-8): sc-374484

SYNM encodes desmuslin, an intermediate filament–associated protein enriched in striated muscle where it helps organize the cytoskeletal network and maintain structural integrity at Z-discs and costameres. Desmuslin participates in pathways governing cytoskeletal anchoring, mechanotransduction, and force transmission by linking filament systems to membrane-associated complexes. Disruption of SYNM has been associated with myofibrillar disorganization and altered muscle fiber stability, making it relevant for studying cytoskeleton-dependent stress responses. As a scaffold-like component of muscle architecture, desmuslin is frequently examined in models of cardiomyopathy and skeletal myopathy to understand how intermediate filament networks preserve cellular resilience.
Desmuslin Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SYNM locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SYNM. 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 SYNM 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 SYNM-disrupted clones.
