CD47 encodes a broadly expressed immunoglobulin superfamily membrane protein that functions as a key regulator of cell–cell communication and self-recognition. Through engagement of SIRPα on myeloid cells, CD47 modulates inhibitory signaling cascades that influence phagocytosis, innate immune surveillance, and inflammatory homeostasis, while also interacting with thrombospondin-1 to affect adhesion and migratory responses. CD47 participates in processes linked to cytoskeletal remodeling and integrin-associated signaling, impacting leukocyte trafficking and tissue remodeling. Dysregulated CD47 expression and signaling have been associated with immune evasion phenotypes in cancer biology and with altered clearance mechanisms in hematologic and inflammatory disease research contexts.
CD47 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CD47 locus in human 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.
