CUG-BP1 Double Nickase Plasmid (h): sc-401383-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- CUG-BP1 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
- CUG-BP1 Double Nickase Plasmid (h) and CUG-BP1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting CELF1. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: CUG-BP1 Antibody (3B1): sc-20003

CELF1 encodes CUG-BP1, an RNA-binding protein that regulates alternative splicing, mRNA stability, and translation through recognition of GU-rich elements in target transcripts. It coordinates post-transcriptional gene regulation across processes such as cell cycle control, stress responses, and differentiation, intersecting with RNA processing pathways and cytoplasmic mRNP dynamics. Dysregulated CELF1 activity has been linked to RNA mis-splicing programs and altered proteostasis, with relevance to disorders involving repeat-associated RNA toxicity and broader aberrations in transcriptome regulation. In human cells, CUG-BP1-dependent networks provide a tractable entry point for dissecting how splicing and RNA turnover shape phenotype.
CUG-BP1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CELF1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CELF1. 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 CELF1 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 CELF1-disrupted clones.
