EOMES CRISPR Activation Plasmid (h): sc-403485-ACT
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- EOMES CRISPR Activation Plasmid (h) is a synergistic activation mediator (SAM) transcription activation system designed to specifically upregulate gene expression
- EOMES CRISPR Activation Plasmid (h) consists of three plasmids at a 1:1:1 mass ratio: a plasmid encoding the deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, and a blasticidin resistance gene; a plasmid encoding the MS2-p65-HSF1 fusion protein, and a hygromycin resistance gene; a plasmid encoding a target-specific 20 nt guide RNA fused to two MS2 RNA aptamers, and a puromycin resistance gene
- The resulting SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by EOMES CRISPR Activation Plasmid (h) and EOMES CRISPR Activation Plasmid (h2) target distinct regulatory regions upstream of the EOMES transcriptional start site. One or both designs may be available
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: EOMES Antibody (1A8): sc-293481

EOMES (eomesodermin) is a T-box transcription factor that orchestrates lineage commitment and differentiation programs during development and in the immune system. In human T and NK cells, EOMES integrates cytokine and TCR-associated signaling to regulate transcriptional networks controlling cytotoxic effector function, memory differentiation, and interferon-γ–linked responses. Its activity intersects with broader gene regulatory circuits that shape cell fate decisions, including chromatin remodeling and transcriptional enhancer usage. Dysregulated EOMES expression has been associated with altered immune cell states and has been investigated in contexts such as tumor immunology, chronic infection, and inflammatory disease mechanisms.
EOMES CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous EOMES expression without altering the underlying DNA sequence.
EOMES CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the EOMES 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 EOMES transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous EOMES expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native EOMES locus and enabling the study of EOMES-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of EOMES pathway restoration in tumor cells with silenced or reduced EOMES expression.
