LRP5 Lentiviral Activation Particles (h) | sc-401331-LAC | 200 µl | $455.00 |
LRP5 (low-density lipoprotein receptor–related protein 5) is a single-pass transmembrane co-receptor that cooperates with Frizzled receptors to transduce canonical Wnt/β-catenin signaling. By regulating β-catenin stabilization and TCF/LEF-dependent transcription, LRP5 influences osteoblast differentiation, bone mass accrual, and tissue homeostasis, and it also contributes to metabolic regulation and vascular biology. Genetic and functional perturbations of LRP5 are associated with skeletal phenotypes and bone density disorders, and altered Wnt/LRP5 signaling has been implicated in tumorigenesis and other pathologies involving dysregulated proliferation and differentiation. LRP5 is therefore widely studied in pathways governing developmental signaling, mechanotransduction in bone, and Wnt-driven transcriptional programs.
LRP5 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 LRP5 upregulation across a broader range of human cell types.
LRP5 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 LRP5 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous LRP5 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native LRP5 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.
