GATA-2 Double Nickase Plasmid (h): sc-400509-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- GATA-2 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
- GATA-2 Double Nickase Plasmid (h) and GATA-2 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting GATA2. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: GATA-2 Antibody (H-6): sc-515178

GATA2 encodes GATA-2, a zinc-finger transcription factor that binds GATA motifs to regulate gene networks controlling hematopoietic stem and progenitor cell maintenance, lineage specification, and endothelial development. Through context-dependent interactions with cofactors such as FOG proteins, GATA-2 coordinates transcriptional programs linked to cytokine signaling, cell-cycle control, and chromatin state transitions during differentiation. Altered GATA2 dosage or function is associated with dysregulated hematopoiesis and immune cell development, and it is frequently studied in models of bone marrow failure and myeloid malignancy. As a nodal regulator of vascular and hematopoietic gene expression, GATA-2 also serves as a useful entry point for interrogating transcriptional circuitry in development and stress responses.
GATA-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GATA2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GATA2. 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 GATA2 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 GATA2-disrupted clones.
