HIF1a Lentiviral Activation Particles (m): sc-420856-LAC
- Target species: mouse
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- HIF1a 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
- HIF1a 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 HIF1a Lentiviral Activation Plasmid (m) and HIF1a Lentiviral Activation Plasmid (m2) target distinct regulatory regions of the Hif1a promoter. One or both designs may be available
- Following transfection, gene activation efficiency can be assayed by WB, IF or IHC using antibody: HIF1a Antibody (28b): sc-13515

Mouse Hif1a encodes the hypoxia-inducible factor 1 alpha (HIF1a), a bHLH-PAS transcription factor that stabilizes under low oxygen and dimerizes with ARNT to coordinate cellular adaptation to hypoxia. HIF1a regulates genes involved in glycolytic metabolism, angiogenic signaling, erythropoiesis, iron homeostasis, and cell survival through hypoxia response elements, integrating inputs from PI3K–AKT–mTOR and MAPK pathways. Its activity is controlled by prolyl hydroxylation and VHL-dependent ubiquitination, linking oxygen sensing to proteostasis. Dysregulated HIF1a signaling is broadly implicated in tumor hypoxia biology, ischemia-related stress responses, chronic inflammation, and metabolic remodeling, making it a central node for mechanistic studies of oxygen-dependent transcriptional programs.
HIF1a 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 Hif1a upregulation across a broader range of human cell types.
HIF1a 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 Hif1a transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous HIF1a expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Hif1a 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.
