HoxA9 Lentiviral Activation Particles (h) | sc-401583-LAC | 200 µl | $455.00 |
HOXA9 encodes the homeobox transcription factor HoxA9, a key regulator of embryonic anterior–posterior patterning and hematopoietic stem and progenitor cell programs. HoxA9 controls lineage commitment, self-renewal, and differentiation through sequence-specific DNA binding and cooperative interactions with cofactors such as PBX and MEIS, shaping transcriptional networks that influence cell-cycle progression and chromatin state. Aberrant HOXA9 expression is strongly associated with disrupted myeloid differentiation and leukemogenic transcriptional circuitry, and it is frequently studied alongside upstream epigenetic regulators that modulate HOX loci. Consequently, HOXA9 is widely used as a model node for interrogating developmental gene regulation, transcriptional reprogramming, and oncogenic pathway dependencies.
HoxA9 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 HOXA9 upregulation across a broader range of human cell types.
HoxA9 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 HOXA9 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous HoxA9 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native HOXA9 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.
