Interleukin-3 is a pleiotropic cytokine that drives the proliferation and differentiation of multipotent hematopoietic progenitors, making it essential for studying early myeloid and mast cell lineage commitment. This recombinant human IL-3 encompasses the full mature sequence (aa 20–152) expressed in *E. coli* with an N-terminal 6xHis tag, and BLI assays confirm binding to human IL-3RA-Fc with a KD of approximately 3.74–3.89 µM, validating receptor engagement suitable for JAK/STAT signaling pathway studies and TF-1 cell proliferation assays. Endotoxin levels below 1.0 EU/µg minimize LPS-driven artifacts in sensitive immune cell functional assays, supporting use in hematopoietic differentiation experiments, antibody development workflows, and as a reference standard in cytokine detection platforms such as ELISA. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, satisfies the quality criteria typical for cell-based activation and proliferation studies where cytokine-specific effects must be clearly distinguished from contaminant-driven responses.
