eIF4E Double Nickase Plasmid (m): sc-420148-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- eIF4E Double Nickase Plasmid (m) 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
- eIF4E Double Nickase Plasmid (m) and eIF4E Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Eif4e. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: eIF4E Antibody (P-2): sc-9976

Mouse Eif4e encodes eIF4E, the cap-binding subunit of the eIF4F translation initiation complex that recognizes the 7-methylguanosine cap and promotes ribosome recruitment to mRNA. eIF4E activity integrates nutrient and growth factor signals through mTORC1–4E-BP regulation and cooperates with MAPK/MNK-dependent phosphorylation to tune selective translation of transcripts involved in proliferation, metabolism, and stress responses. Altered eIF4E abundance or regulation is linked to translational reprogramming and dysregulated cell growth programs, making Eif4e a key node for studying post-transcriptional control in cancer biology and developmental phenotypes. In mouse models, perturbing Eif4e supports mechanistic dissection of cap-dependent translation, proteostasis, and signaling-coupled gene expression.
eIF4E Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Eif4e locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Eif4e. 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 Eif4e 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 Eif4e-disrupted clones.
