Interleukin-3 drives the proliferation and differentiation of multipotent hematopoietic progenitors and mast cells, making it a critical tool for dissecting lineage commitment and cytokine-dependent survival pathways in primary human cells. This recombinant protein, spanning the full mature sequence (aa 20–152), demonstrates robust bioactivity with an ED50 of 0.4476–1.272 ng/mL in TF-1 cell proliferation assays, providing a quantitative benchmark for dose-response studies in cell-based functional screens and JAK/STAT signaling pathway investigations. The endotoxin level of less than 1.0 EU/μg eliminates LPS-driven artifacts that confound immune cell activation experiments, supporting its use in primary PBMC differentiation assays and in vivo inflammation models where cytokine-specific effects must be isolated from innate immune noise. Purity exceeding 90% by SDS-PAGE, combined with the validated proliferative potency, aligns with standards expected in antibody development workflows, including immunogen preparation and ELISA standard curve generation.
