p53 Lentiviral Activation Particles (h): sc-416469-LAC
- Target species: human
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- p53 Lentiviral Activation Particles (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically and efficiently upregulate gene expression via lentiviral transduction of cells
- p53 Lentiviral Activation Particles (h) 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 p53 Lentiviral Activation Plasmid (h) and p53 Lentiviral Activation Plasmid (h2) target distinct regulatory regions of the TP53 promoter. One or both designs may be available
- Following transfection, gene activation efficiency can be assayed by WB, IF or IHC using antibody: p53 Antibody (DO-1): sc-126

Human TP53 encodes p53, a sequence-specific transcription factor that integrates DNA damage sensing, oncogenic stress, and other cellular insults to coordinate cell-cycle arrest, apoptosis, senescence, and DNA repair. p53 governs core checkpoint pathways through transcriptional control of targets such as CDKN1A (p21), BAX, PUMA, and GADD45, and is tightly regulated by ubiquitin-mediated turnover via MDM2/MDM4. It also interfaces with PI3K–AKT, MAPK, and metabolic stress programs to preserve genome stability and limit propagation of damaged cells. Dysregulation of TP53 signaling through mutation, copy-number alteration, or pathway-level inhibition is a central feature of tumor biology and is widely studied in mechanisms of genomic instability, treatment response phenotypes in model systems, and cell fate decisions.
p53 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 TP53 upregulation across a broader range of human cell types.
p53 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 TP53 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous p53 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native TP53 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.
