GM-CSF is a critical hematopoietic cytokine that drives myeloid cell proliferation, dendritic cell differentiation, and macrophage activation through JAK2/STAT5 and MAPK signaling cascades. This recombinant human CSF2 demonstrates high signaling potency, with an ED50 of 21.07–35.48 pg/mL in a TF-1 proliferation assay, confirming robust biological activity suitable for dose-response functional studies, monocyte-to-dendritic-cell differentiation protocols, and JAK/STAT pathway activation experiments. The full-length mature protein (18–144 aa) is expressed in yeast with an N-terminal 6xHis tag, achieving greater than 95% purity by SDS-PAGE and endotoxin levels below 1.0 EU/μg — a threshold that supports use in immune cell assays where LPS contamination would confound cytokine-specific readouts. These specifications also provide a suitable basis for antibody validation workflows, ELISA standard curve generation, and in vivo studies of myeloid biology or tumor immunology.
