HLX1 Lentiviral Activation Particles (h) | sc-403700-LAC | 200 µl | $455.00 |
Human HLX (HLX1) encodes a homeobox transcription factor that regulates lineage specification and transcriptional programs during embryonic development and hematopoiesis. HLX1 influences cell fate decisions by coordinating gene expression networks involved in differentiation, tissue patterning, and immune cell maturation, with downstream effects on proliferation and survival. Dysregulated HLX expression has been linked to altered developmental pathways and aberrant hematopoietic states, making it relevant for mechanistic studies of transcriptional control in normal and disease-associated contexts.
HLX1 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 HLX upregulation across a broader range of human cell types.
HLX1 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 HLX transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous HLX1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native HLX 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.
