Description
IL-1α is a potent upstream mediator of innate immunity and sterile inflammation, and this tag-free recombinant form of the mature human protein (113–271 aa) delivers exceptional signaling potency with an ED50 below 1.0 pg/ml in a murine D10S proliferation assay, corresponding to a specific activity exceeding 1.0 × 10⁹ IU/mg. This level of bioactivity supports use in cell-based functional assays such as T-cell proliferation, NF-κB and MAPK pathway activation studies, and macrophage or dendritic cell differentiation experiments where precise dose–response relationships are essential. Endotoxin levels below 1.0 EU/μg, confirmed by LAL testing, minimize LPS-driven artifacts that can confound cytokine-specific readouts in primary immune cell cultures and in vivo inflammation models. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin control, also provides a suitable basis for use as a reference standard in cytokine detection assays or as a positive control in ELISA-based antibody validation.
