Fibronectin Lentiviral Activation Particles (m) | sc-420394-LAC | 200 µl | $455.00 |
Mouse Fn1 encodes fibronectin, a high-molecular-weight extracellular matrix glycoprotein that organizes fibrillar networks and regulates cell adhesion, migration, and mechanotransduction through integrin engagement. Fibronectin influences focal adhesion dynamics, cytoskeletal remodeling, and signaling pathways including FAK/Src, MAPK, and PI3K–AKT, shaping tissue architecture during development and wound repair. In biomedical research, altered FN1 expression and matrix deposition are frequently examined in contexts of fibrosis, inflammation, angiogenesis, and tumor-associated stromal remodeling, where extracellular matrix cues modulate cell fate and immune cell trafficking.
Fibronectin 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 Fn1 upregulation across a broader range of human cell types.
Fibronectin 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 Fn1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Fibronectin expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Fn1 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.
