ZFHX4 Lentiviral Activation Particles (m) | sc-429838-LAC | 200 µl | $455.00 |
Zfhx4 encodes ZFHX4, a large multi–zinc finger homeobox transcription factor that regulates gene expression programs linked to neuronal differentiation, axon guidance, and maintenance of cell identity. By binding DNA and coordinating transcriptional networks, ZFHX4 can influence chromatin-associated regulatory processes and developmental signaling pathways that shape lineage commitment. Altered ZFHX4 expression has been reported in studies of neurodevelopmental phenotypes and in molecular profiling of several tumor contexts, making it a useful target for interrogating transcriptional control in disease-relevant models. In mouse systems, Zfhx4 is commonly investigated for its contributions to neural development and for how transcription factor–driven programs intersect with proliferation and differentiation states.
ZFHX4 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 Zfhx4 upregulation across a broader range of human cell types.
ZFHX4 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 Zfhx4 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous ZFHX4 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Zfhx4 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.
