HMG-1/HMGB1 Double Nickase Plasmid (m): sc-420871-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- HMG-1/HMGB1 Double Nickase Plasmid (m) 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
- HMG-1/HMGB1 Double Nickase Plasmid (m) and HMG-1/HMGB1 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Hmgb1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: HMG-1/HMGB1 Antibody (HAP46.5): sc-56698

Mouse Hmgb1 encodes the chromatin-associated protein HMG-1/HMGB1, a DNA-binding architectural factor that bends and stabilizes nucleoprotein complexes to modulate transcription, replication, recombination, and DNA repair. HMGB1 participates in chromatin remodeling and damage response pathways, including coordination of base excision repair and double-strand break repair signaling, and can influence inflammatory signaling when released extracellularly. Dysregulated HMGB1 activity has been linked to aberrant cytokine responses, neuroinflammation, and tumor biology, making it a frequent target in studies of innate immunity, stress responses, and genome maintenance. In mouse models, Hmgb1 perturbation is used to interrogate cell death programs, sterile inflammation, and transcriptional control in development and disease-relevant contexts.
HMG-1/HMGB1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Hmgb1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Hmgb1. 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 Hmgb1 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 Hmgb1-disrupted clones.
