IL-13 drives Th2-mediated immune responses including alternative macrophage activation, IgE class switching, and airway hyperresponsiveness, making it a critical target in allergy and fibrosis research. This tag-free recombinant mouse IL-13 (aa 26–131) demonstrates strong signaling potency with an ED50 of 1.93 ng/mL in a TF-1 cell proliferation assay, supporting use in cell-based functional studies such as STAT6 phosphorylation kinetics, B-cell differentiation assays, 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 immune cell readouts, making this preparation appropriate for in vivo murine models of allergic inflammation or fibrosis as well as antibody development workflows including ELISA coating and positive controls. Purity exceeding 95% by SDS-PAGE, combined with faithful coverage of the mature sequence, provides a suitable basis for mechanistic JAK/STAT pathway dissection without interference from fusion tags.
