RORγ Lentiviral Activation Particles (m): sc-422700-LAC
- Target species: mouse
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- RORγ Lentiviral Activation Particles (m) is a synergistic activation mediator (SAM) transcription activation system designed to specifically and efficiently upregulate gene expression via lentiviral transduction of cells
- RORγ Lentiviral Activation Particles (m) contain the following SAM Activation elements: a deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, an MS2-p65-HSF1 fusion protein and a target-specific 20 nt guide RNA. They also contain the blasticidin, hygromycin and puromycin resistance genes
- Upon transduction, the SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by RORγ Lentiviral Activation Plasmid (m) and RORγ Lentiviral Activation Plasmid (m2) target distinct regulatory regions of the Rorc promoter. One or both designs may be available
- Following transfection, gene activation efficiency can be assayed by WB, IF or IHC using antibody: RORγ Antibody (27.92): sc-293150

Rorc encodes the nuclear receptor RORγ, a ligand-regulated transcription factor that binds ROR response elements to coordinate tissue- and context-specific gene expression programs. In the immune system, RORγt isoform activity is central to differentiation and maintenance of Th17 cells and group 3 innate lymphoid cells, linking cytokine networks such as IL-17/IL-23 signaling to inflammatory transcriptional circuits. RORγ also contributes to thymocyte development and broader metabolic and circadian-associated regulatory pathways through nuclear receptor signaling. Dysregulated Rorc/RORγ activity has been implicated in models of autoimmunity and chronic inflammation, making it a widely used node for mechanistic studies of T cell fate decisions and mucosal immunity.
RORγ 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 Rorc upregulation across a broader range of human cell types.
RORγ 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 Rorc transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous RORγ expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Rorc 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.
