G9a Lentiviral Activation Particles (m): sc-430994-LAC
- Target species: mouse
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- G9a 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
- G9a 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 G9a Lentiviral Activation Plasmid (m) and G9a Lentiviral Activation Plasmid (m2) target distinct regulatory regions of the Ehmt2 promoter. One or both designs may be available
- Following transfection, gene activation efficiency can be assayed by WB, IF or IHC using antibody: G9a Antibody (C-9): sc-515726

Mouse Ehmt2 encodes the lysine methyltransferase G9a (EHMT2), a principal writer of H3K9me1/2 marks that promote facultative heterochromatin formation and stable gene repression. G9a coordinates epigenetic silencing programs that shape lineage commitment, embryonic development, and maintenance of cell identity through crosstalk with DNA methylation and chromatin remodeling complexes. By regulating transcriptional networks tied to cell-cycle control, DNA damage responses, and metabolic state, Ehmt2 influences diverse nuclear pathways that govern differentiation and stress adaptation. Dysregulated G9a activity and H3K9 methylation patterns are frequently studied in contexts of oncogenic transcriptional reprogramming, fibrosis-related gene expression changes, and neurodevelopmental phenotypes in model systems.
G9a 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 Ehmt2 upregulation across a broader range of human cell types.
G9a 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 Ehmt2 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous G9a expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Ehmt2 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.
