IL-5 drives eosinophil differentiation, survival, and activation, making it a critical tool for dissecting JAK2/STAT5 signaling in allergic inflammation and hypereosinophilic disease models. This recombinant human IL-5, spanning the full mature sequence (aa 20–134) with a C-terminal 6xHis tag, demonstrates potent bioactivity with an ED50 of 0.1–0.5 ng/mL in TF-1 cell proliferation assays, confirming reliable performance in functional studies including eosinophil differentiation, immune cell activation, and antibody validation workflows such as ELISA standard curves or blocking assays. Mammalian expression preserves native folding and post-translational modifications essential for receptor engagement, while endotoxin levels below 1.0 EU/μg eliminate LPS-driven artifacts that confound cytokine-specific readouts in sensitive immune cell cultures. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, supports use in in vivo inflammation models and as a reference standard in cytokine detection platforms.
