Interleukin-15 drives T cell and NK cell proliferation, survival, and effector function, making it a central regulator in both adaptive and innate immunity. This tag-free recombinant protein, spanning the full mature sequence (aa 49–162), demonstrates potent bioactivity in CTLL-2 cytotoxic T cell proliferation assays with an ED50 ≤0.5 ng/ml, providing a quantitative benchmark for dose-response studies in primary lymphocyte cultures, PBMC activation experiments, and NK cell expansion protocols. The endotoxin level of ≤10 EU/mg meets the contamination thresholds commonly required for immune cell functional assays, where LPS artifacts can confound cytokine-specific signaling through JAK1/JAK3/STAT5 and PI3K/AKT pathways. Purity exceeding 95% by SDS-PAGE, combined with the validated proliferative potency, supports its use as a positive control in cytokine detection platforms, an immunogen for antibody generation, and a reference standard in studies of T cell memory differentiation and tumor immunotherapy models.
