ABC1 Lentiviral Activation Particles (h) | sc-401086-LAC | 200 µl | $455.00 |
Human ABCA1 (ABC1) is an ATP-binding cassette transporter that mediates the efflux of cholesterol and phospholipids to apolipoprotein A-I, initiating nascent HDL biogenesis and maintaining cellular lipid homeostasis. ABC1 activity influences reverse cholesterol transport and intersects with liver X receptor (LXR)/retinoid X receptor signaling, membrane microdomain composition, and macrophage foam cell formation. By regulating intracellular sterol burden, ABCA1 impacts inflammatory signaling and oxidative stress responses in lipid-laden cells. Dysregulation or loss of ABCA1 function is linked to impaired HDL formation and lipid accumulation phenotypes relevant to atherosclerosis biology and metabolic disease research.
ABC1 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 ABCA1 upregulation across a broader range of human cell types.
ABC1 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 ABCA1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous ABC1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native ABCA1 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.
