Interleukin-3 is a pleiotropic cytokine that drives the proliferation and differentiation of multipotent hematopoietic progenitors, mast cells, and myeloid lineages, making it indispensable for studying early hematopoiesis and immune cell development. This tag-free recombinant mouse IL-3 (residues 33–166) encompasses the mature protein sequence and demonstrates exceptional potency, with an ED50 below 0.05 ng/mL in M-NFS-60 proliferation assays—corresponding to a specific activity exceeding 2 × 10⁷ IU/mg—providing a reliable basis for dose-dependent proliferation studies, mast cell expansion, and JAK/STAT or MAPK signaling pathway dissection. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts, which supports use in sensitive immune cell functional assays, primary bone marrow progenitor differentiation experiments, and in vivo murine models of inflammation or hematopoietic reconstitution. Purity exceeding 98% by SDS-PAGE further satisfies the criteria expected for ELISA reference standards and antibody validation workflows.
