GM-CSF drives the proliferation and differentiation of myeloid progenitors and modulates the activation state of mature granulocytes and macrophages, making it a central regulator in both homeostatic hematopoiesis and inflammatory responses. This tag-free protein, spanning the full mature sequence (aa 18–144), demonstrates potent bioactivity with an ED50 ≤0.2 ng/mL in TF-1 cell proliferation assays, providing a quantitative benchmark for dose-response studies in cell-based functional screens and signaling pathway investigations targeting JAK/STAT or MAPK activation. Endotoxin levels ≤10 EU/mg satisfy the contamination thresholds typical for primary immune cell cultures and in vivo inflammation models, where LPS artifacts would confound interpretation of GM-CSF-specific effects. Purity exceeding 95% by SDS-PAGE, combined with the validated proliferative activity, supports its use as a positive control in cytokine detection platforms and as a reference standard in antibody development workflows.
