IFNB1 encodes human interferon-β (IFN-β), a type I interferon secreted in response to viral infection and nucleic acid sensing through pattern-recognition receptors such as RIG-I–like receptors and cGAS–STING. IFN-β signals via the IFNAR receptor to activate JAK–STAT pathways and induce interferon-stimulated genes that shape antiviral restriction, antigen presentation, and innate–adaptive immune crosstalk. This program influences cell-intrinsic stress responses and cytokine networks, with dysregulation linked to aberrant inflammatory signaling and altered host defense. IFNB1/IFN-β biology is therefore frequently interrogated in models of infection, interferonopathies, and immune-mediated pathologies to dissect upstream sensing and downstream transcriptional responses.
IFN-β Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the IFNB1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within IFNB1. 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 IFNB1 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 IFNB1-disrupted clones.
