SULT2B1 Lentiviral Activation Particles (m) | sc-424817-LAC | 200 µl | $455.00 |
Mouse Sult2b1 encodes the cytosolic sulfotransferase SULT2B1, an enzyme that catalyzes 3′-phosphoadenosine-5′-phosphosulfate (PAPS)-dependent sulfation of hydroxysteroids and oxysterols, including cholesterol and related sterols. By converting lipophilic sterols into more polar sulfated metabolites, SULT2B1 helps regulate sterol homeostasis, membrane composition, and steroid hormone availability, with downstream effects on nuclear receptor signaling and lipid metabolic programs. SULT2B1 activity is linked to pathways governing epidermal differentiation and barrier formation, macrophage lipid handling, and hepatic lipid metabolism, making it relevant to studies of inflammation, metabolic dysfunction, and disorders of cholesterol/sterol balance.
SULT2B1 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 Sult2b1 upregulation across a broader range of human cell types.
SULT2B1 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 Sult2b1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous SULT2B1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Sult2b1 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.
