IL-6 orchestrates acute-phase responses and drives the transition from innate to adaptive immunity, making it a central node in inflammation and oncogenesis research. This recombinant protein, spanning the full mature sequence (aa 30–212) and expressed in yeast with an N-terminal 6xHis tag, demonstrates dose-dependent proliferative activity in human TF-1 cells with an ED50 of 58–295 pg/mL, confirming receptor engagement at physiologically relevant concentrations and supporting its use in cell-based proliferation assays with primary T cells, B cells, and PBMCs. The low endotoxin level (< 1.0 EU/μg) is critical for preventing LPS-induced artifacts in immune cell activation studies, particularly when dissecting JAK/STAT3 and NF-κB signaling pathways or evaluating cytokine-driven differentiation. Purity exceeding 95% by SDS-PAGE, combined with validated bioactivity, provides a suitable basis for antibody development workflows, including immunogen preparation and ELISA standard curve generation in cytokine detection platforms.
