M-CSF Double Nickase Plasmid (m) | sc-419838-NIC | 20 µg | $410.00 |
Colony stimulating factor 1 (Csf1) encodes macrophage colony-stimulating factor (M-CSF), a secreted cytokine that controls survival, proliferation, and differentiation of monocyte/macrophage lineage cells through CSF1R signaling. M-CSF activates downstream PI3K–AKT, MAPK/ERK, and JAK/STAT pathways to shape innate immune homeostasis, osteoclastogenesis, and tissue remodeling. In mouse systems, altered Csf1/M-CSF activity is closely linked to dysregulated myeloid development, inflammatory microenvironments, and bone turnover phenotypes, making it a central node for studying macrophage biology. These processes are frequently leveraged in models of chronic inflammation, neuroinflammation and microglial dynamics, and tumor-associated macrophage polarization without implying therapeutic outcomes.
M-CSF Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Csf1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Csf1. 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 Csf1 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 Csf1-disrupted clones.
