MC4-R Double Nickase Plasmid (h): sc-417769-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- MC4-R 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
- MC4-R Double Nickase Plasmid (h) and MC4-R Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting MC4R. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: MC4-R Antibody (C-10): sc-55567

MC4R encodes melanocortin-4 receptor (MC4-R), a G protein–coupled receptor that integrates α-MSH and related melanocortin signals to regulate neuronal control of energy balance and feeding behavior. MC4-R primarily couples to Gs to stimulate adenylyl cyclase and cAMP/PKA-dependent transcriptional programs, and it interfaces with hypothalamic leptin–POMC circuitry and broader neuroendocrine homeostatic networks. Altered MC4R signaling is strongly associated with dysregulated appetite and body weight phenotypes, making it a key node in studies of metabolic regulation. In cellular and organismal models, MC4R perturbation is used to map GPCR signaling, receptor trafficking/desensitization, and downstream transcriptional responses linked to energy homeostasis.
MC4-R Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MC4R locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MC4R. 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 MC4R 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 MC4R-disrupted clones.
