PRL-R Lentiviral Activation Particles (h) | sc-400814-LAC | 200 µl | $455.00 |
PRLR encodes the prolactin receptor (PRL-R), a class I cytokine receptor that binds prolactin to regulate epithelial differentiation, lactogenic signaling, and tissue homeostasis in multiple organs. Ligand-induced receptor dimerization activates JAK2/STAT5 as well as PI3K/AKT and MAPK/ERK pathways, coordinating transcriptional programs linked to proliferation, survival, and hormone-responsive gene expression. PRLR signaling is widely studied in the context of endocrine regulation and immune modulation, and dysregulation of PRL-R pathway activity has been associated with altered growth control and oncogenic phenotypes in hormone-responsive tissues. As a result, PRLR is frequently interrogated as a node connecting cytokine receptor signaling to context-dependent transcriptional outputs and disease-relevant cellular behaviors.
PRL-R 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 PRLR upregulation across a broader range of human cell types.
PRL-R 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 PRLR transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous PRL-R expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native PRLR 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.
