Interleukin-2 is a central driver of T cell proliferation and homeostasis, making its recombinant form essential for dissecting JAK/STAT5 signaling, regulatory T cell differentiation, and lymphocyte expansion protocols. This tag-free mouse IL-2, encompassing the full mature sequence (residues 21–169), demonstrates an ED50 below 0.2 ng/ml in CTLL-2 proliferation assays—corresponding to a specific activity exceeding 5.0 × 10⁶ IU/mg—which provides a suitable basis for dose-sensitive functional studies, including primary T cell activation assays, in vivo tumor immunology models, and use as a reference standard in cytokine detection platforms. Endotoxin levels held below 1.0 EU/μg by LAL testing minimize LPS-driven artifacts that can confound immune cell readouts, while purity exceeding 95% by SDS-PAGE supports use in antibody validation workflows such as ELISA standard curves and Western blot positive controls. The E. coli-derived, untagged format ensures that observed biological responses are attributable to IL-2 signaling rather than tag-mediated interference.
