CD274/PD-L1 Double Nickase Plasmid (m): sc-425636-NIC
- Target species: mouse
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- CD274/PD-L1 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
- CD274/PD-L1 Double Nickase Plasmid (m) and CD274/PD-L1 Double Nickase Plasmid (m2) encode distinct paired gRNA designs targeting Cd274. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: CD274/PD-L1 Antibody (D-8): sc-518027

Mouse Cd274 encodes CD274/PD-L1, a type I transmembrane immune checkpoint ligand that binds PD-1 (PDCD1) and dampens T cell receptor signaling, cytokine production, and cytotoxic activity. PD-L1 expression is induced by inflammatory cues such as IFN-γ through JAK/STAT signaling and integrates with NF-κB–driven programs that shape antigen presentation and immune tolerance in tissues. In hematopoietic and non-hematopoietic cells, CD274 contributes to regulation of peripheral tolerance, adaptive immune homeostasis, and the balance between effector and regulatory responses. Dysregulated PD-L1 expression is widely associated with immune evasion in cancer models and with altered immune phenotypes in settings of chronic inflammation and autoimmunity, making Cd274 a key node for immunology and tumor microenvironment research.
CD274/PD-L1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Cd274 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Cd274. 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 Cd274 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 Cd274-disrupted clones.
