GM-CSF drives myeloid cell proliferation, differentiation, and activation through JAK2/STAT5 and MAPK signaling, making it indispensable for immune cell functional studies. This recombinant human CSF2 spans the full mature sequence (aa 18–144) with a C-terminal 6xHis tag and demonstrates potent bioactivity, with an ED50 of 6–30 pg/ml in TF-1 cell proliferation assays—confirming signaling competence suitable for dose-response experiments, dendritic cell differentiation protocols, and JAK/STAT pathway activation studies. Endotoxin levels below 1.0 EU/μg eliminate LPS-driven artifacts that confound cytokine-specific readouts in primary monocyte and macrophage assays, supporting use in sensitive in vivo inflammation models and as a reference standard in GM-CSF detection assays. Mammalian-expressed with greater than 95% purity by SDS-PAGE, this protein provides a suitable basis for antibody validation workflows including ELISA coating and Western blot positive controls.
