Na+ CP type IIIα Lentiviral Activation Particles (m) | sc-422820-LAC | 200 µl | $455.00 |
Scn3a encodes the mouse voltage-gated sodium channel α subunit Na+ CP type IIIα (Nav1.3), a pore-forming membrane protein that supports action potential initiation and propagation in excitable cells. By mediating rapid, transient Na+ influx, Nav1.3 contributes to neuronal membrane depolarization, firing patterns, and network excitability, integrating with ion homeostasis and activity-dependent signaling pathways. Scn3a expression is dynamically regulated during development and after neural injury, and altered channel activity has been linked to hyperexcitability phenotypes relevant to epilepsy, pain processing, and neurodevelopmental disorders. These properties make Scn3a a useful target for dissecting sodium channel contributions to circuit function and excitability-driven disease mechanisms in mouse models.
Na+ CP type IIIα 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 Scn3a upregulation across a broader range of human cell types.
Na+ CP type IIIα 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 Scn3a transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Na+ CP type IIIα expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Scn3a 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.
