IGF-1 Receptor α/β/IGF1R Double Nickase Plasmid (m2) | sc-421057-NIC-2 | 20 µg | $410.00 |
Igf1r encodes the insulin-like growth factor 1 receptor (IGF-1R), a receptor tyrosine kinase synthesized as an α/β heterotetramer that binds IGF-1 and IGF-2 to initiate mitogenic and pro-survival signaling. Upon ligand engagement and autophosphorylation, IGF-1R activates PI3K–AKT–mTOR and RAS–RAF–MEK–ERK pathways, coordinating glucose metabolism, protein synthesis, cell-cycle progression, and resistance to apoptosis. In mouse biology, Igf1r is central to embryonic and postnatal growth, tissue regeneration, and stem/progenitor cell maintenance, with strong cross-talk to insulin receptor signaling and feedback control via IRS proteins. Dysregulated IGF-1R signaling is widely used as a model axis in studies of oncogenic transformation, metastasis-associated phenotypes, and metabolic or developmental disorders, where pathway rewiring can be interrogated in defined genetic backgrounds.
IGF-1 Receptor α/β/IGF1R Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Igf1r locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Igf1r. 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 Igf1r 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 Igf1r-disrupted clones.
