STEAP2 Double Nickase Plasmid (h): sc-410402-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- STEAP2 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
- STEAP2 Double Nickase Plasmid (h) and STEAP2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting STEAP2. One or both designs may be available

STEAP2 (six transmembrane epithelial antigen of the prostate 2) is a membrane-associated metalloreductase enriched in prostate epithelium that catalyzes ferric and cupric ion reduction, supporting cellular iron and copper uptake and redox homeostasis. By modulating metal availability, STEAP2 influences oxidative stress responses, mitochondrial metabolism, and proliferative signaling programs linked to iron-dependent enzymatic processes. Dysregulated STEAP2 expression has been reported in prostate and other malignancies, where altered metal metabolism can reshape tumor cell growth, differentiation, and invasiveness. As a surface-localized redox enzyme, STEAP2 is also useful for studying endosomal/secretory trafficking and metal-dependent pathway crosstalk in human cells.
STEAP2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the STEAP2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within STEAP2. 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 STEAP2 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 STEAP2-disrupted clones.
