ARP Double Nickase Plasmid (m) | sc-428989-NIC | 20 µg | $410.00 |
Mesencephalic astrocyte-derived neurotrophic factor (Manf) is an endoplasmic reticulum–resident, stress-inducible protein that supports proteostasis and secretory pathway homeostasis in mammalian cells. In mouse, MANF is closely linked to the unfolded protein response and ER-associated quality control, modulating cellular survival programs under ER stress and perturbations in protein folding. Altered MANF signaling has been studied in contexts of neurodegeneration, metabolic stress, and inflammatory tissue injury, where ER stress and cell-type vulnerability intersect. These attributes make Manf a useful node for probing ER stress adaptation, secretory cell function, and stress-linked transcriptional remodeling in biomedical models.
ARP Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Manf locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Manf. 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 Manf 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 Manf-disrupted clones.
