IGF-I Double Nickase Plasmid (m) | sc-421056-NIC | 20 µg | $410.00 |
Mouse Igf1 encodes insulin-like growth factor I (IGF-I), a secreted peptide hormone that regulates somatic growth, cell survival, and metabolic homeostasis in endocrine and paracrine contexts. IGF-I signals primarily through IGF1R to activate PI3K–AKT–mTOR and RAS–RAF–MEK–ERK pathways, coordinating protein synthesis, glucose utilization, and cell-cycle progression. In tissues such as muscle, liver, bone, and brain, IGF-I integrates growth hormone cues with local microenvironmental signals to shape development, regeneration, and differentiation programs. Dysregulated IGF-I signaling is widely studied in models of growth abnormalities, insulin sensitivity, aging-related phenotypes, and proliferative signaling relevant to oncogenic pathway crosstalk.
IGF-I Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Igf1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Igf1. 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 Igf1 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 Igf1-disrupted clones.
