SOCS-3 Double Nickase Plasmid (m) | sc-419666-NIC | 20 µg | $410.00 |
Mouse Socs3 encodes suppressor of cytokine signaling 3 (SOCS-3), a rapid feedback inhibitor that attenuates cytokine and growth factor signaling by binding JAK kinases and targeting signaling complexes for ubiquitin-mediated turnover. SOCS-3 is strongly induced downstream of STAT activation and restrains JAK/STAT signaling in immune and metabolic tissues, shaping inflammatory outputs, macrophage polarization, and acute phase responses. Through modulation of pathways linked to IL-6 family cytokines and leptin signaling, SOCS-3 influences insulin sensitivity, energy homeostasis, and tissue stress responses. Dysregulated SOCS-3 expression or activity is frequently studied in contexts of chronic inflammation, metabolic syndrome, and cancer-associated cytokine networks where signaling amplitude and duration are critical variables.
SOCS-3 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Socs3 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Socs3. 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 Socs3 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 Socs3-disrupted clones.
