Description
Lymphotoxin-alpha drives NF-κB and MAPK signaling through TNFR1/TNFR2 engagement, making it a critical tool for dissecting TNF superfamily biology in controlled cell-based systems. This tag-free recombinant human LTA, encompassing the full mature sequence (aa 35–205), demonstrates exceptional cytotoxic potency with an ED50 below 5 pg/ml in murine L929 cells, corresponding to a specific activity exceeding 2.0 × 10⁸ IU/mg — providing a reliable reference standard for cytokine detection assays and a potent stimulus for apoptosis and NF-κB activation studies. Endotoxin levels below 1.0 EU/μg ensure that downstream responses in primary immune cell assays, PBMC activation experiments, or in vivo inflammation models reflect genuine LTA-mediated signaling rather than LPS-driven artifacts. Purity exceeding 96% by SDS-PAGE further supports use as a coating antigen in ELISA-based antibody validation or as a functional positive control in signaling pathway characterization.
