ZIP4 Double Nickase Plasmid (h): sc-412558-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- ZIP4 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
- ZIP4 Double Nickase Plasmid (h) and ZIP4 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting SLC39A4. One or both designs may be available

SLC39A4 encodes ZIP4, a plasma membrane zinc importer that regulates cellular zinc uptake and distribution, supporting zinc-dependent enzyme activity and transcriptional programs. ZIP4 activity contributes to metal ion homeostasis and influences pathways linked to epithelial differentiation, barrier integrity, and nutrient sensing through zinc-responsive signaling. Dysregulation of SLC39A4 is associated with impaired zinc absorption and altered epithelial physiology, making it relevant to studies of micronutrient transport and tissue homeostasis. In biomedical research, ZIP4 serves as a useful node for interrogating zinc-driven gene regulation and stress responses in gastrointestinal and epithelial model systems.
ZIP4 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SLC39A4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SLC39A4. 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 SLC39A4 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 SLC39A4-disrupted clones.
