PARP-2 Double Nickase Plasmid (m) | sc-419019-NIC | 20 µg | $410.00 |
Mouse Parp2 encodes PARP-2, a DNA damage sensor and poly(ADP-ribose) polymerase that contributes to genome maintenance by catalyzing ADP-ribosylation of chromatin-associated proteins. PARP-2 participates in base excision repair and single-strand break repair, coordinating repair factor recruitment, chromatin remodeling, and restoration of replication integrity. Through crosstalk with PARP-1, XRCC1-associated repair complexes, and stress signaling pathways, PARP-2 helps modulate cell-cycle checkpoints and cellular responses to genotoxic stress. Dysregulated PARP-2 activity or altered PARylation dynamics is relevant to studies of genome instability, inflammatory signaling, and cancer biology in mouse models.
PARP-2 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Parp2 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Parp2. 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 Parp2 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 Parp2-disrupted clones.
