IMPDH2 Lentiviral Activation Particles (h) | sc-410835-LAC | 200 µl | $455.00 |
IMPDH2 encodes inosine-5′-monophosphate dehydrogenase 2, a rate-limiting enzyme in the de novo guanine nucleotide biosynthesis pathway that converts IMP to XMP, supporting cellular pools of GMP and GTP. By controlling nucleotide availability, IMPDH2 influences DNA and RNA synthesis, cell-cycle progression, and metabolic adaptation during proliferation and immune activation. Its activity links purine metabolism to transcriptional and translational capacity, with downstream effects on replication stress and mitochondrial function. Dysregulated IMPDH2 expression or flux through guanine nucleotide synthesis has been associated with proliferative phenotypes and altered immune cell function, making it a relevant target for studying metabolic dependencies in disease-relevant cellular models.
IMPDH2 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 IMPDH2 upregulation across a broader range of human cell types.
IMPDH2 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 IMPDH2 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous IMPDH2 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native IMPDH2 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.
