GM-CSF drives myeloid cell proliferation, differentiation, and activation through JAK2/STAT5 and MAPK signaling, making it indispensable for studying innate immune responses and hematopoiesis. This recombinant human CSF2 (aa 18–144, full-length mature protein) demonstrates high signaling potency with an ED50 of 28.1–63.8 pg/mL in TF-1 proliferation assays, confirming robust biological activity 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 immune cell functional assays, supporting use in PBMC stimulation, in vivo inflammation models, and as a reference standard in cytokine detection platforms. Expressed in mammalian cells with an N-terminal 6xHis tag, this protein provides native-like glycosylation and exceeds 95% purity by SDS-PAGE, satisfying the quality criteria typical for antibody validation workflows and cell-based signaling experiments.
