SLC35B4 Lentiviral Activation Particles (h) | sc-413728-LAC | 200 µl | $455.00 |
SLC35B4 encodes a Golgi/ER-associated nucleotide sugar transporter that mediates import of UDP-xylose and UDP-N-acetylglucosamine into the lumen of the secretory pathway, supporting glycosylation and proteoglycan biosynthesis. By controlling availability of activated sugars for glycosyltransferases, SLC35B4 influences glycan maturation, extracellular matrix organization, and glycan-dependent receptor signaling. Altered nucleotide sugar transport and downstream glycosylation programs are implicated in metabolic dysregulation and in cancer-associated changes to cell adhesion, migration, and immune recognition. Accordingly, SLC35B4 is studied in pathways linking Golgi homeostasis and carbohydrate metabolism to cell-surface glycome remodeling and disease-relevant phenotypes.
SLC35B4 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 SLC35B4 upregulation across a broader range of human cell types.
SLC35B4 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 SLC35B4 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous SLC35B4 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native SLC35B4 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.
