OB-cadherin Lentiviral Activation Particles (h): sc-401051-LAC
- Target species: human
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- OB-cadherin Lentiviral Activation Particles (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically and efficiently upregulate gene expression via lentiviral transduction of cells
- OB-cadherin Lentiviral Activation Particles (h) contain the following SAM Activation elements: a deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, an MS2-p65-HSF1 fusion protein and a target-specific 20 nt guide RNA. They also contain the blasticidin, hygromycin and puromycin resistance genes
- Upon transduction, the SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by OB-cadherin Lentiviral Activation Plasmid (h) and OB-cadherin Lentiviral Activation Plasmid (h2) target distinct regulatory regions of the CDH11 promoter. One or both designs may be available
- Following transfection, gene activation efficiency can be assayed by WB, IF or IHC using antibody: OB-cadherin Antibody (F-3): sc-365867

CDH11 encodes OB-cadherin, a calcium-dependent cell–cell adhesion molecule that supports homophilic interactions and cadherin–catenin complex formation at adherens junctions. Through coupling to actin remodeling and junctional signaling, OB-cadherin influences cell polarity, migration, and tissue morphogenesis, and can modulate pathways linked to epithelial–mesenchymal transition and stromal organization. In human tissues, CDH11 is prominently studied in mesenchymal lineages such as osteoblasts and fibroblasts, where it contributes to extracellular matrix remodeling and intercellular mechanical coupling. Dysregulated CDH11 expression has been associated with pathological tissue remodeling and invasive behavior in several disease contexts, motivating its use as a marker and functional node in adhesion- and fibrosis-related research.
OB-cadherin 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 CDH11 upregulation across a broader range of human cell types.
OB-cadherin 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 CDH11 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous OB-cadherin expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native CDH11 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.
