Annexin V Double Nickase Plasmid (h): sc-400836-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Annexin V 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
- Annexin V Double Nickase Plasmid (h) and Annexin V Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting ANXA5. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: Annexin V Antibody (H-3): sc-74438

ANXA5 encodes Annexin V, a Ca²⁺-dependent phospholipid-binding protein that preferentially associates with phosphatidylserine on the inner leaflet of the plasma membrane and redistributes during membrane remodeling. Annexin V participates in calcium-regulated membrane trafficking, vesicle dynamics, and cytoskeletal organization, and is widely used as a molecular readout of phosphatidylserine externalization during apoptosis. Through its roles at the membrane–cytoskeleton interface, Annexin V is linked to pathways governing cell survival, inflammation, and coagulation-related surfaces. Dysregulated ANXA5 expression and phosphatidylserine exposure phenotypes have been studied in cancer biology, autoimmune contexts, and vascular-associated mechanisms, supporting its relevance as a functional node in stress and cell death signaling.
Annexin V Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ANXA5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ANXA5. 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 ANXA5 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 ANXA5-disrupted clones.
