Granulocyte colony-stimulating factor drives neutrophil lineage commitment and mobilization, making it a critical tool for dissecting myeloid differentiation and emergency granulopoiesis. This tag-free protein, spanning residues 31–204 of the mature human sequence, demonstrates potent bioactivity with an ED50 below 0.5 ng/ml in NFS-60 cell proliferation assays, corresponding to a specific activity exceeding 1 × 10⁷ units/mg—a threshold that supports dose-response studies in primary hematopoietic progenitor cultures and JAK/STAT signaling pathway investigations. Endotoxin levels remain at or below 10 EU/mg, meeting the contamination criteria typical for immune cell functional assays where LPS artifacts would confound cytokine-specific responses. The combination of greater than 95% purity and validated proliferative activity provides a suitable basis for antibody development workflows, including use as an immunogen or ELISA standard in cytokine detection platforms.
