IL-27 Lentiviral Activation Particles (m) | sc-434233-LAC | 200 µl | $455.00 |
Mouse Il27 encodes IL-27, a heterodimeric cytokine in the IL-12 family produced primarily by antigen-presenting cells and acting through the IL-27 receptor complex (WSX-1/IL27RA and gp130). IL-27 activates JAK/STAT signaling, with prominent STAT1 and STAT3 phosphorylation, shaping T helper differentiation, limiting excessive Th17-driven inflammation, and promoting regulatory programs including IL-10 induction in specific contexts. Through these pathways, IL-27 influences innate and adaptive immune crosstalk, antigen presentation, and interferon-associated transcriptional networks. Dysregulated IL-27 signaling has been implicated in models of autoimmunity, chronic inflammation, and infection, making Il27 a useful node for mechanistic immunology studies and pathway mapping.
IL-27 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 Il27 upregulation across a broader range of human cell types.
IL-27 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 Il27 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous IL-27 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Il27 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.
