Interleukin-3 is a pleiotropic cytokine that drives proliferation and differentiation of multipotent hematopoietic progenitors, making it essential for studies of early myeloid and mast cell lineage commitment. This recombinant human IL-3, spanning the full mature sequence (aa 20–152) with a C-terminal 6×His tag, demonstrates high signaling potency with an ED50 of 0.3–1.5 ng/mL in TF-1 cell proliferation assays, confirming its suitability for functional studies of JAK/STAT and MAPK pathway activation. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts, which supports use in sensitive immune cell differentiation assays, in vivo hematopoiesis models, and as a reference standard in cytokine detection platforms. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, satisfies the criteria typical for antibody validation workflows including ELISA coating and positive control applications.
