NFKBIA/IkB alpha Lentiviral Activation Particles (h) | sc-400034-LAC | 200 µl | $455.00 |
NFKBIA encodes IκBα, a key inhibitory regulator of NF-κB signaling that binds RELA/p50 complexes in the cytoplasm and restricts their nuclear translocation. Upon inflammatory or stress-induced activation of the IKK complex, IκBα is phosphorylated, ubiquitinated, and degraded, enabling rapid transcription of NF-κB target genes involved in cytokine production, innate immunity, apoptosis, and cell survival. NFKBIA is also a direct NF-κB transcriptional target, forming a negative-feedback loop that shapes signal amplitude and duration. Dysregulated IκBα control is implicated in chronic inflammation and oncogenic NF-κB activity, making NFKBIA a common node studied across immune signaling, tumor biology, and cell fate regulation.
NFKBIA/IkB alpha 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 NFKBIA upregulation across a broader range of human cell types.
NFKBIA/IkB alpha 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 NFKBIA transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous NFKBIA/IkB alpha expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native NFKBIA 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.
