OAZ Lentiviral Activation Particles (m) | sc-430124-LAC | 200 µl | $455.00 |
Zfp423 encodes the transcriptional regulator OAZ (also known as ZNF423), a multi–zinc finger protein that functions as a DNA-binding scaffold integrating developmental signaling cues into cell type–specific gene expression programs in mouse. OAZ participates in transcriptional networks linked to neurodevelopment and adipocyte lineage commitment, and has been implicated in crosstalk with pathways such as BMP/SMAD and related differentiation-associated transcriptional control. By coordinating enhancer and promoter interactions, Zfp423 helps regulate progenitor state transitions, cellular fate specification, and maturation across multiple tissues. Dysregulated Zfp423/OAZ activity is therefore relevant to studies of developmental disorders, altered differentiation, and disease-associated changes in transcriptional circuitry.
OAZ 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 Zfp423 upregulation across a broader range of human cell types.
OAZ 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 Zfp423 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous OAZ expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Zfp423 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.
