HLA-F Double Nickase Plasmid (h2) | sc-410821-NIC-2 | 20 µg | $410.00 |
HLA-F encodes a non-classical MHC class I molecule that participates in immune surveillance by modulating interactions between antigen-presenting cells and lymphocyte receptors, including inhibitory and activating NK cell receptors. Unlike highly polymorphic classical HLA class I proteins, HLA-F exhibits restricted polymorphism and is linked to regulation of immune tolerance, inflammatory signaling, and cellular stress responses. HLA-F expression is dynamic in activated immune cells and can influence antigen presentation context, innate immune activation thresholds, and cytokine-driven pathways in the microenvironment. Dysregulated HLA-F has been associated with altered immune evasion phenotypes and immune infiltration patterns reported across inflammatory conditions and multiple cancers, supporting its use in mechanistic immunology studies.
HLA-F Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HLA-F locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HLA-F. 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 HLA-F 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 HLA-F-disrupted clones.
