NAG Lentiviral Activation Particles (h): sc-412223-LAC
- Target species: human
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- NAG Lentiviral Activation Particles (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically and efficiently upregulate gene expression via lentiviral transduction of cells
- NAG Lentiviral Activation Particles (h) contain the following SAM Activation elements: a deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, an MS2-p65-HSF1 fusion protein and a target-specific 20 nt guide RNA. They also contain the blasticidin, hygromycin and puromycin resistance genes
- Upon transduction, the SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by NAG Lentiviral Activation Plasmid (h) and NAG Lentiviral Activation Plasmid (h2) target distinct regulatory regions of the NBAS promoter. One or both designs may be available

NBAS encodes neuroblastoma amplified sequence protein, a large cytosolic factor that functions in Golgi-to-ER retrograde trafficking through its association with the NRZ tethering complex (NBAS–RINT1–ZW10) and coordination of vesicle capture and fusion. By supporting ER homeostasis and protein quality control, NBAS influences secretory pathway integrity and cellular responses to proteostasis stress. Genetic variation in NBAS has been linked to multisystem phenotypes that include recurrent liver dysfunction and immune-related abnormalities, highlighting its relevance to studies of ER stress, intracellular transport, and tissue vulnerability to proteotoxic challenges.
NAG 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 NBAS upregulation across a broader range of human cell types.
NAG 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 NBAS transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous NAG expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native NBAS 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.
