SPN encodes CD43 (leukosialin), a heavily O-glycosylated sialomucin expressed on most hematopoietic cells that regulates leukocyte adhesion, migration, and activation. CD43 modulates immune synapse architecture and cell–cell interactions by influencing integrin-dependent adhesion, cytoskeletal dynamics, and signaling downstream of antigen receptors in T cells and B cells. Through its effects on trafficking and activation thresholds, CD43 contributes to inflammatory responses and immune homeostasis across myeloid and lymphoid lineages. Altered CD43 expression or glycoform composition is frequently evaluated in immune dysregulation and hematologic malignancy research as a marker linked to differentiation state and aberrant signaling.
CD43 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SPN locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SPN. 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 SPN 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 SPN-disrupted clones.
