Cd47 encodes CD47, a broadly expressed immunoglobulin superfamily receptor that functions as a “don’t eat me” signal through binding to SIRPα on macrophages, thereby modulating phagocytosis and innate immune checkpoints. CD47 also interacts with thrombospondin-1 to influence integrin signaling, cell adhesion, migration, and nitric oxide–dependent vascular responses. In mouse tissues, CD47 contributes to homeostatic clearance of cells, regulation of inflammatory signaling, and shaping of tumor–immune interactions. Dysregulated CD47 signaling has been implicated in immune evasion, chronic inflammation, and altered hematopoietic and vascular biology, making it a relevant node for mechanistic studies of immune surveillance pathways.
CD47 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Cd47 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Cd47. 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 Cd47 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 Cd47-disrupted clones.
