UHRF1 Double Nickase Plasmid (h): sc-403851-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- UHRF1 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
- UHRF1 Double Nickase Plasmid (h) and UHRF1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting UHRF1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: UHRF1 Antibody (H-8): sc-373750

UHRF1 (ubiquitin-like with PHD and RING finger domains 1) is a multidomain epigenetic regulator that coordinates maintenance DNA methylation and chromatin state inheritance during S phase. By recognizing hemimethylated CpG sites and histone H3 marks, UHRF1 recruits and stimulates DNMT1 and interfaces with histone ubiquitination and deacetylation machinery to preserve transcriptional programs. Its activity supports cell-cycle progression, replication-coupled chromatin assembly, and genome stability through regulation of heterochromatin organization and DNA damage responses. Dysregulated UHRF1 expression and altered UHRF1-dependent methylation patterns are frequently linked to aberrant silencing of tumor suppressor pathways and broader epigenomic remodeling in cancer biology.
UHRF1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the UHRF1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within UHRF1. 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 UHRF1 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 UHRF1-disrupted clones.
