Interleukin-2 is a central driver of T cell proliferation and homeostasis, making precise recombinant sourcing essential for mechanistic immunology work. This tag-free recombinant mouse IL-2, covering the full mature sequence (aa 21–169), demonstrates a specific activity of ≥1×10⁷ IU/mg in a CTLL-2 cytotoxic T cell proliferation assay, confirming robust signaling potency suitable for JAK/STAT pathway dissection, primary T cell expansion, and differentiation studies. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound immune cell activation readouts, supporting use in sensitive functional assays as well as in vivo murine models of inflammation or tumor biology. Produced in *E. coli* with greater than 95% purity by SDS-PAGE, this protein provides a suitable basis for applications including ELISA standard curves, antibody validation, and dose-response proliferation assays where sequence fidelity and low background activation are critical.
