USP22 Double Nickase Plasmid (h): sc-403660-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- USP22 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
- USP22 Double Nickase Plasmid (h) and USP22 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting USP22. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: USP22 Antibody (C-3): sc-390585

Human USP22 encodes a ubiquitin-specific protease that functions as the deubiquitinating module of the SAGA transcriptional coactivator complex, where it removes ubiquitin from histone H2B and additional substrates to modulate chromatin accessibility and gene expression. Through these activities, USP22 helps coordinate transcriptional programs linked to cell cycle progression, DNA damage responses, and maintenance of proteostasis. USP22 has been connected to oncogenic transcriptional signatures and altered differentiation states across multiple tumor types, making it a common target for mechanistic studies of epigenetic regulation and transcriptional control. Its role at the intersection of ubiquitin signaling and chromatin remodeling also supports research into how deubiquitination influences genome stability and stress-adaptive pathways.
USP22 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the USP22 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within USP22. 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 USP22 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 USP22-disrupted clones.
