IL-13 is a pleiotropic type 2 cytokine central to allergic inflammation, fibrosis, and alternative macrophage activation, making precise functional reagents essential for dissecting JAK/STAT6 signaling in murine disease models. This recombinant mouse IL-13 (residues 22–131, C-terminal 6xHis tag) demonstrates an ED50 of 11.34 ng/ml in TF-1 cell proliferation assays, confirming robust signaling potency suitable for cell-based functional studies including immune cell differentiation, STAT6 phosphorylation kinetics, and dose-response calibration as a reference standard in cytokine detection platforms. Endotoxin levels below 1.0 EU/μg eliminate LPS-driven artifacts that confound macrophage polarization and T-cell activation readouts, supporting use in sensitive in vivo models of airway inflammation or fibrosis as well as antibody development workflows requiring clean coating antigens. Mammalian expression preserves native folding and post-translational modifications, while purity exceeding 95% by SDS-PAGE aligns with standards expected in quantitative signaling pathway analyses.
