SAP 18 Lentiviral Activation Particles (h) | sc-404214-LAC | 200 µl | $455.00 |
SAP18 (SAP 18) encodes a core component of transcriptional repression machinery that interfaces with histone deacetylation and chromatin remodeling to modulate gene expression programs. SAP18 associates with the Sin3/HDAC complex and contributes to epigenetic control of cell cycle progression, differentiation, and stress-responsive transcription. Through these interactions, SAP18 helps coordinate pathways governing RNA processing and genome stability-linked transcriptional outputs. Dysregulated SAP18-dependent repression has been investigated in the context of aberrant chromatin states relevant to cancer biology and other disorders involving altered epigenetic regulation.
SAP 18 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 SAP18 upregulation across a broader range of human cell types.
SAP 18 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 SAP18 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous SAP 18 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native SAP18 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.
