Wee 1 Lentiviral Activation Particles (h) | sc-400701-LAC | 200 µl | $455.00 |
WEE1 encodes the Wee1 kinase, a central regulator of the G2/M checkpoint that restrains CDK1–cyclin B activity by inhibitory phosphorylation, delaying mitotic entry until DNA replication and repair are complete. Wee1 integrates signals from ATR/CHK1-driven replication stress responses and coordinates cell-cycle progression with genome integrity maintenance, influencing S-phase dynamics, checkpoint signaling, and mitotic catastrophe. Dysregulated WEE1 activity has been linked to altered proliferation control and heightened dependence on checkpoint pathways in genomically unstable cell states. As a result, WEE1 is widely studied in the context of DNA damage response circuitry, chromosomal instability, and mechanisms shaping cell fate under replicative stress.
Wee 1 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 WEE1 upregulation across a broader range of human cell types.
Wee 1 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 WEE1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Wee 1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native WEE1 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.
