CD137L CRISPR/Cas9 KO Plasmid (m) | sc-423455 | 20 µg | $397.00 |
Tnfsf9 encodes CD137L (4-1BBL), a TNF superfamily ligand expressed primarily on antigen-presenting cells that engages CD137 (TNFRSF9) to deliver potent costimulatory cues to T cells and other immune effectors. CD137L–CD137 signaling promotes NF-κB and MAPK pathway activation, supporting T-cell expansion, survival, cytokine production, and the shaping of memory responses, with additional effects on dendritic cell maturation and myeloid cell function. In mouse models, Tnfsf9 activity is implicated in regulation of inflammatory circuits and immune homeostasis, influencing contexts such as autoimmunity, chronic inflammation, and tumor immune surveillance. These roles make CD137L a useful node for dissecting costimulation-dependent immune phenotypes and antigen-driven responses.
CD137L CRISPR/Cas9 KO Plasmid (m) is a pool of plasmids designed for targeted disruption of the Tnfsf9 gene in mouse cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the Tnfsf9 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 Tnfsf9 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 CD137L protein expression.
This CRISPR knockout system enables efficient generation of Tnfsf9-deficient cell models for investigation of CD137L signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
