MEK-5 Double Nickase Plasmid (h): sc-401688-NIC
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- MEK-5 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
- MEK-5 Double Nickase Plasmid (h) and MEK-5 Double Nickase Plasmid (h2) encode distinct paired gRNA designs targeting MAP2K5. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: MEK-5 Antibody (E-3): sc-365198

MAP2K5 encodes MEK-5, a dual-specificity MAP kinase kinase that preferentially phosphorylates and activates ERK5 (MAPK7) to regulate transcriptional programs linked to proliferation, differentiation, stress adaptation, and cytoskeletal remodeling. MEK-5–ERK5 signaling integrates inputs from growth factor and environmental cues and influences downstream factors such as MEF2 family transcription regulators, shaping cell survival and motility responses. Dysregulation of the MAP2K5/ERK5 axis has been associated with altered signal transduction in contexts including oncogenic pathway rewiring, cardiovascular biology, and inflammatory signaling, making MAP2K5 a useful node for dissecting pathway crosstalk. In human cell models, perturbing MEK-5 activity supports mechanistic studies of MAPK network specificity and compensatory signaling across parallel MAPK cascades.
MEK-5 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the MAP2K5 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within MAP2K5. 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 MAP2K5 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 MAP2K5-disrupted clones.
