Interleukin-5 is a central regulator of eosinophil differentiation, activation, and survival, making it a critical target in studies of allergic inflammation and type 2 immune responses. This tag-free recombinant mouse IL-5, encompassing the full mature sequence (residues 21–133), demonstrates strong signaling potency with an ED50 below 2 ng/ml in TF-1 cell proliferation assays, corresponding to a specific activity exceeding 5.0 × 10⁵ IU/mg — a level that supports use in JAK/STAT signaling pathway dissection, eosinophil differentiation studies, and as a reference standard in cytokine detection assays. Endotoxin levels below 1.0 EU/μg minimize the risk of LPS-driven artifacts in sensitive immune cell functional assays, while purity exceeding 98% by SDS-PAGE provides a suitable basis for in vivo murine models of airway inflammation and for antibody development workflows including immunization, ELISA coating, and positive control applications.
