PDC-E2 Double Nickase Plasmid (h2) | sc-402520-NIC-2 | 20 µg | $410.00 |
Human DLAT encodes dihydrolipoamide S-acetyltransferase (PDC-E2), the E2 catalytic core of the mitochondrial pyruvate dehydrogenase complex that converts pyruvate-derived carbon into acetyl-CoA to fuel the TCA cycle and oxidative phosphorylation. PDC-E2 mediates acyl-group transfer via its lipoyl domains and coordinates metabolic flux between glycolysis and mitochondrial respiration, influencing NADH production and redox balance. Perturbation of DLAT/PDC-E2 function is linked to impaired energy metabolism and mitochondrial dysfunction, and PDC-E2 is also a well-characterized autoantigen in primary biliary cholangitis, connecting its biology to immune-associated pathology.
PDC-E2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DLAT locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DLAT. 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 DLAT 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 DLAT-disrupted clones.
