CFTR Lentiviral Activation Particles (h) | sc-400653-LAC | 200 µl | $455.00 |
Human CFTR (cystic fibrosis transmembrane conductance regulator) encodes an ATP-binding cassette transporter that functions as a cAMP/PKA-regulated chloride and bicarbonate channel at the apical membrane of epithelial cells. By controlling anion flux, CFTR coordinates epithelial fluid secretion, airway surface hydration, and the ionic composition of mucus, with downstream effects on mucociliary clearance and barrier homeostasis. CFTR activity integrates with pathways governing ion transport and membrane trafficking, including phosphorylation-dependent channel gating and regulated endocytosis/recycling. Dysregulation of CFTR expression or function is strongly associated with epithelial transport defects and is widely studied in the context of cystic fibrosis biology and related airway, intestinal, and pancreatic phenotypes.
CFTR 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 CFTR upregulation across a broader range of human cell types.
CFTR 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 CFTR transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous CFTR expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native CFTR 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.
