Interleukin-21 plays a central role in T cell, B cell, and NK cell regulation, making precise recombinant forms essential for dissecting JAK/STAT3 and MAPK signaling cascades in murine immune models. This tag-free recombinant mouse IL-21 encompasses the full mature sequence (18–146 aa) and demonstrates strong signaling potency, with an ED50 below 25 ng/ml in a human N1186 T cell proliferation assay corresponding to a specific activity exceeding 4.0 × 10⁴ IU/mg — providing a reliable reference standard for cytokine detection assays and a functional driver for T and B cell proliferation, differentiation, and activation studies. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts, which supports use in sensitive primary immune cell cultures and in vivo murine models of inflammation or tumor biology. Purity exceeding 98% by SDS-PAGE, combined with this endotoxin profile, aligns with standards expected in antibody development workflows including use as a coating antigen or ELISA positive control.
