DNA pol γ Lentiviral Activation Particles (m) | sc-422341-LAC | 200 µl | $455.00 |
Mouse Polg encodes DNA polymerase gamma, the sole replicative polymerase for mitochondrial DNA, supporting mtDNA replication, repair, and maintenance of genome integrity within mitochondria. DNA pol gamma functions with its accessory subunit to ensure processive synthesis and proofreading, linking Polg activity to oxidative phosphorylation capacity and mitochondrial biogenesis. Disruption of POLG function is associated with mtDNA depletion or multiple deletions, impaired respiratory chain function, and cellular stress responses that impact energy-intensive tissues. As a central node in mitochondrial genome stability, Polg is widely studied in pathways connecting nucleotide metabolism, replication stress, and mitochondrial dysfunction relevant to neurodegeneration, myopathy, and aging models.
DNA pol γ Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Polg upregulation across a broader range of human cell types.
DNA pol γ Lentiviral Activation Particles (m) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the Polg transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous DNA pol γ expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Polg genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
