DDX60 Lentiviral Activation Particles (h) | sc-408255-LAC | 200 µl | $455.00 |
DDX60 encodes an interferon-inducible DExD/H-box RNA helicase that functions as a cytosolic sensor and amplifier of antiviral innate immunity. It participates in RIG-I–like receptor signaling and type I interferon pathways by promoting recognition and processing of viral RNA and enhancing downstream transcriptional programs that restrict replication. Through its RNA binding and helicase activities, DDX60 influences RNA metabolism and the magnitude of ISG expression during cellular stress and infection. Dysregulated DDX60 expression has been linked to altered antiviral responses and inflammatory signaling, making it relevant for studies of host–pathogen interactions and immune-associated disease mechanisms.
DDX60 Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient DDX60 upregulation across a broader range of human cell types.
DDX60 Lentiviral Activation Particles (h) 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 DDX60 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous DDX60 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native DDX60 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.
