GM-CSF drives the proliferation and differentiation of myeloid progenitors, making it indispensable for generating bone marrow-derived dendritic cells and studying JAK/STAT5 signaling in murine immune models. This tag-free recombinant mouse Csf2, encompassing the full mature sequence (aa 18–141) expressed in *E. coli*, demonstrates potent bioactivity with an ED50 of 15–50 pg/mL in a PDC-P1 proliferation assay, confirming robust signaling capacity suitable for dose-response studies and functional differentiation experiments. Endotoxin levels below 1.0 EU/μg eliminate LPS-driven artifacts that confound cytokine-specific readouts in sensitive assays such as macrophage polarization, NF-κB pathway activation, and in vivo inflammation models. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, supports use as a reference standard in GM-CSF detection assays and as a reliable positive control for antibody validation by ELISA.
