TNFSF15 (also known as TL1A) plays a critical role in modulating immune responses and promoting apoptosis in tumor biology, making it a valuable tool for cancer-related functional studies. This tag-free recombinant human TNFSF15, spanning residues 72–251, demonstrates potent pro-apoptotic activity with an ED50 of less than 20 ng/mL in TF-1 cell apoptosis assays, corresponding to a specific activity exceeding 5.0 × 10⁴ IU/mg—providing a reliable reference for cell-based functional assays, NF-κB and MAPK signaling pathway dissection, and in vivo tumor biology models. Endotoxin levels below 1.0 EU/μg ensure that apoptotic and inflammatory readouts reflect genuine TNFSF15 signaling rather than LPS-driven artifacts, which is essential when working with sensitive immune cell populations. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin control, supports use as a positive control in cytokine detection assays and as an immunogen or coating antigen for antibody development campaigns.
