KLF15 Lentiviral Activation Particles (h) | sc-402267-LAC | 200 µl | $455.00 |
KLF15 (Krüppel-like factor 15) encodes a zinc-finger transcription factor that binds GC-rich promoter elements to coordinate context-dependent gene programs controlling cellular differentiation, metabolic homeostasis, and stress-responsive transcription. In human tissues, KLF15 integrates hormonal and nutrient signaling to modulate pathways involved in gluconeogenic regulation, lipid utilization, and mitochondrial energy balance, and it also contributes to muscle and cardiac transcriptional remodeling. Dysregulated KLF15 expression has been linked to altered metabolic phenotypes and maladaptive tissue responses in cardiovascular and skeletal muscle contexts, making it a useful node for studying transcriptional control of energy metabolism and cell-state transitions. As a transcriptional regulator with broad downstream targets, KLF15 is frequently interrogated to map gene networks that couple environmental cues to epigenetic and promoter-level outputs.
KLF15 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 KLF15 upregulation across a broader range of human cell types.
KLF15 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 KLF15 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous KLF15 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native KLF15 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.
