Mrf-1 Double Nickase Plasmid (h): sc-406689-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Mrf-1 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
- Mrf-1 Double Nickase Plasmid (h) and Mrf-1 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting ARID5A. One or both designs may be available

ARID5A encodes the AT-rich interactive domain-containing protein Mrf-1, a nucleic acid–binding regulator implicated in control of inflammatory gene expression and RNA metabolism. Mrf-1 has been linked to modulation of cytokine signaling outputs, including IL-6–associated transcriptional programs, and can influence stability and translation of select immune transcripts. Through these activities, ARID5A contributes to innate and adaptive immune cell responses and broader stress-responsive gene regulation networks. Dysregulated ARID5A/Mrf-1 activity has been associated with chronic inflammation and immune-mediated pathologies, supporting its relevance for mechanistic studies in inflammatory signaling and gene regulatory circuitry.
Mrf-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ARID5A locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ARID5A. 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 ARID5A 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 ARID5A-disrupted clones.
