TREM-2 CRISPR Activation Plasmid (h) | sc-401585-ACT | 20 µg | $397.00 |
TREM2 encodes triggering receptor expressed on myeloid cells 2 (TREM-2), an immunoreceptor primarily expressed in microglia and other myeloid lineages that modulates innate immune sensing, phagocytosis, and lipid handling. Through association with the adaptor TYROBP/DAP12, TREM-2 signals via SYK-dependent pathways to influence cytokine production, chemotaxis, survival, and metabolic reprogramming during tissue surveillance. In the central nervous system, TREM-2 contributes to microglial responses to cellular debris and aggregated proteins, linking it to neuroinflammatory processes and risk mechanisms implicated in neurodegenerative disorders. Dysregulated TREM-2 signaling is also studied in macrophage polarization and tumor-associated myeloid biology, supporting pathway-focused research in inflammation and immune regulation.
TREM-2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TREM2 expression without altering the underlying DNA sequence.
TREM-2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TREM2 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the TREM2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous TREM-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TREM2 locus and enabling the study of TREM-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of TREM-2 pathway restoration in tumor cells with silenced or reduced TREM2 expression.
