Notch 3 Lentiviral Activation Particles (m) | sc-421933-LAC | 200 µl | $455.00 |
Notch3 encodes Notch 3, a single-pass transmembrane receptor that mediates juxtacrine signaling controlling cell fate decisions, differentiation, and tissue homeostasis. Upon ligand engagement, proteolytic processing releases the Notch intracellular domain to regulate transcriptional programs via RBPJ/CSL complexes, integrating with pathways governing proliferation and lineage commitment. In mouse systems, Notch3 activity is especially relevant to vascular smooth muscle biology, neurodevelopmental processes, and immune cell function, and dysregulated signaling is widely used as a model axis for studying context-dependent oncogenic and developmental phenotypes. Because Notch signaling is highly dose- and timing-dependent, precise modulation of endogenous Notch3 is important for dissecting pathway cross-talk and transcriptional network dynamics.
Notch 3 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 Notch3 upregulation across a broader range of human cell types.
Notch 3 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 Notch3 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Notch 3 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Notch3 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.
