Type I 5-phosphatase Double Nickase Plasmid (h): sc-410836-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Type I 5-phosphatase 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
- Type I 5-phosphatase Double Nickase Plasmid (h) and Type I 5-phosphatase Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting INPP5A. One or both designs may be available

INPP5A encodes type I inositol polyphosphate 5-phosphatase, a cytosolic enzyme that hydrolyzes the 5-phosphate from inositol 1,4,5-trisphosphate (IP3) and related inositol phosphates to terminate second-messenger signaling. By limiting IP3-dependent calcium mobilization from the endoplasmic reticulum, INPP5A modulates Ca2+-regulated processes including secretion, excitability, and activity-dependent transcriptional responses. This phosphoinositide/inositol phosphate turnover intersects with PI3K-linked signaling and broader homeostatic control of cellular stress responses. Altered INPP5A expression or function has been implicated in dysregulated calcium signaling and is studied in the context of neurobiology and cancer-associated signaling rewiring.
Type I 5-phosphatase Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the INPP5A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within INPP5A. 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 INPP5A 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 INPP5A-disrupted clones.
