apolipoprotein E/apoE Double Nickase Plasmid (m): sc-419167-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- apolipoprotein E/apoE 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
- apolipoprotein E/apoE Double Nickase Plasmid (m) and apolipoprotein E/apoE Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Apoe. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: apolipoprotein E/apoE Antibody (F-9): sc-390925

Mouse Apoe encodes apolipoprotein E (apoE), a secreted lipid-binding protein that mediates cholesterol and triglyceride transport by associating with lipoprotein particles and engaging LDL receptor family members. ApoE regulates lipoprotein uptake, macrophage lipid handling, and inflammatory signaling, integrating pathways such as lipoprotein clearance, reverse cholesterol transport, and microglial responses in the central nervous system. In mouse models, Apoe status strongly influences atherosclerotic plaque biology, hepatic lipid metabolism, and neuroimmune phenotypes linked to amyloid deposition and synaptic maintenance. These functions make Apoe a core node for studying cardiometabolic disease mechanisms and neurodegeneration-relevant lipid and immune crosstalk in vivo and in primary cells.
apolipoprotein E/apoE Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Apoe locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Apoe. 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 Apoe 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 Apoe-disrupted clones.
