IL-31 is a key pruritogenic and pro-inflammatory cytokine that signals through the IL-31RA/OSMR heterodimer to drive JAK/STAT, MAPK, and PI3K pathways implicated in atopic dermatitis, pruritus, and airway hypersensitivity. This tag-free recombinant human IL-31 encompasses the full mature sequence (residues 24–164) and demonstrates robust signaling potency, effectively inducing STAT3 activation in human U-87 MG cells at just 5 ng/mL — a level of activity that supports use in cell-based functional assays such as STAT3 phosphorylation readouts, keratinocyte or neuronal activation studies, and in vivo models of itch and allergic inflammation. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts in sensitive immune cell experiments, making this protein appropriate for antibody development workflows, ELISA standard curves, and signaling pathway dissection. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin control, satisfies the quality thresholds commonly required for quantitative receptor-binding and dose–response studies.
