IL-13 is a pleiotropic type 2 cytokine central to allergic inflammation, fibrosis, and alternative macrophage activation, making precise functional studies dependent on highly active recombinant material. This mouse IL-13 (aa 26–131, C-terminal 6xHis tag) demonstrates an ED50 of 2–13 ng/mL in TF-1 cell proliferation assays, confirming signaling potency suitable for JAK/STAT6 pathway dissection, Th2-driven differentiation studies, and dose–response standardization in cytokine detection platforms. Endotoxin levels below 1.0 EU/μg eliminate LPS-driven artifacts that confound readouts in primary macrophage polarization experiments and in vivo murine models of airway inflammation or fibrosis. Mammalian-cell expression preserves native folding of the mature sequence, and purity exceeding 95% by SDS-PAGE alongside stringent endotoxin control supports use as a reference standard in ELISA development or as a functional antigen for antibody validation workflows.
