G-CSF drives granulopoiesis and neutrophil mobilization through JAK/STAT and MAPK signaling, making it a critical tool for studying myeloid differentiation and tumor microenvironment biology. This tag-free recombinant human CSF3 (residues 31–204 of Isoform 2) demonstrates exceptional signaling potency with an ED50 of 0.03 ng/mL in NFS-60 cell proliferation assays, confirming robust biological activity suitable for dose-response studies, myeloid differentiation experiments, and JAK/STAT pathway activation analyses. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts, which supports use in sensitive immune cell functional assays and in vivo tumor biology models where confounding innate immune activation must be excluded. The protein's greater than 95% purity by SDS-PAGE, combined with its validated potency, provides a suitable basis for deployment as a reference standard in G-CSF detection assays or as a positive control in antibody validation workflows.
