Human ALPI encodes intestinal alkaline phosphatase (IAP), a brush-border ectoenzyme that dephosphorylates luminal substrates and contributes to epithelial barrier homeostasis. IAP activity intersects with mucosal innate immune regulation by detoxifying pro-inflammatory phosphorylated microbial products and shaping host–microbe interactions, thereby influencing downstream inflammatory signaling in the gut. ALPI expression is tightly linked to enterocyte differentiation and nutrient handling, and altered IAP activity has been associated with intestinal inflammation and dysbiosis-related phenotypes in experimental systems. As a functional marker of small intestinal epithelium, ALPI is frequently used to interrogate pathways governing barrier integrity, microbial sensing, and epithelial maturation.
IAP Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ALPI locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ALPI. 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 ALPI 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 ALPI-disrupted clones.
