TREX-1 CRISPR/Cas9 KO Plasmid (m) | sc-423502 | 20 µg | $397.00 |
Trex1 encodes TREX-1, a 3′→5′ DNA exonuclease that degrades aberrant cytosolic DNA arising from endogenous retroelements, replication stress, or DNA damage, thereby limiting inappropriate activation of innate immune sensors. By restraining cGAS–STING signaling and downstream type I interferon transcriptional programs, TREX-1 helps maintain immune homeostasis and prevents chronic inflammatory responses to self nucleic acids. In mouse systems, Trex1 loss is commonly used to model nucleic acid–driven autoinflammation and to interrogate mechanisms linking genome instability, cell death pathways, and interferon-stimulated gene expression. TREX-1 activity also intersects with DNA repair and replication-associated processes, making it relevant for studies of genotoxic stress and immune surveillance.
TREX-1 CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Trex1 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Trex1 together with the Streptococcus pyogenes Cas9 nuclease. The plasmids also encode GFP, allowing fluorescent identification and enrichment of successfully transfected cells by fluorescence microscopy or flow cytometry.
The multi-guide design increases the likelihood of generating insertions or deletions (indels) that disrupt the Trex1 open reading frame following Cas9-mediated double-strand break formation. DNA breaks introduced by the CRISPR/Cas9 system are repaired through endogenous non-homologous end joining (NHEJ) pathways, frequently resulting in frameshift mutations that abolish TREX-1 protein expression.
This CRISPR knockout system enables efficient generation of Trex1-deficient cell models for investigation of TREX-1 signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
