CEACAM5 Lentiviral Activation Particles (h) | sc-401219-LAC | 200 µl | $455.00 |
CEACAM5 encodes carcinoembryonic antigen-related cell adhesion molecule 5, a GPI-anchored immunoglobulin superfamily member that mediates homophilic and heterophilic adhesion at the cell surface. It contributes to epithelial tissue organization, polarity, and barrier-associated signaling by modulating cell–cell contacts and interacting with extracellular matrix and immune receptors. CEACAM5 also interfaces with pathways controlling proliferation, differentiation, and microbial recognition, with downstream effects on inflammatory signaling and epithelial stress responses. Dysregulated CEACAM5 expression is frequently studied in the context of epithelial transformation and metastasis biology, as well as host–pathogen interactions in mucosal tissues.
CEACAM5 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 CEACAM5 upregulation across a broader range of human cell types.
CEACAM5 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 CEACAM5 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous CEACAM5 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native CEACAM5 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.
