Aquaporin 1/AQP1 Lentiviral Activation Particles (h) | sc-400340-LAC | 200 µl | $455.00 |
Human AQP1 encodes aquaporin 1, a tetrameric membrane water channel that enables rapid osmotic water transport across plasma membranes and specialized barriers. AQP1 contributes to fluid homeostasis and microvascular permeability and is integrated with processes such as endothelial transport, cell volume regulation, and tissue fluid balance. Beyond water flux, AQP1 has been linked to cell migration and angiogenic behaviors in certain contexts, connecting channel activity with cytoskeletal dynamics and extracellular microenvironment interactions. Dysregulated AQP1 expression or localization has been reported in disorders involving abnormal fluid handling and vascular barrier function, supporting its utility as a research target in edema-related biology, kidney and lung physiology, and tumor microenvironment studies.
Aquaporin 1/AQP1 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 AQP1 upregulation across a broader range of human cell types.
Aquaporin 1/AQP1 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 AQP1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Aquaporin 1/AQP1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native AQP1 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.
