Ska1 Double Nickase Plasmid (h): sc-415109-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Ska1 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
- Ska1 Double Nickase Plasmid (h) and Ska1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting SKA1. One or both designs may be available

SKA1 encodes spindle and kinetochore associated complex subunit 1 (Ska1), a core component of the SKA complex that couples end-on kinetochore–microtubule attachments to depolymerizing spindle microtubules during mitosis. Ska1 supports stable chromosome alignment, spindle checkpoint silencing, and timely anaphase onset, thereby maintaining genome integrity through accurate chromosome segregation. Disruption of SKA complex function can promote chromosomal instability and aneuploidy, processes frequently studied in the context of proliferative disorders and tumor cell evolution. Accordingly, SKA1 is widely used as a molecular entry point to interrogate kinetochore dynamics, mitotic checkpoint control, and cell-cycle progression in human cells.
Ska1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SKA1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SKA1. 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 SKA1 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 SKA1-disrupted clones.
