Description
GM-CSF is a critical hematopoietic cytokine that drives granulocyte and macrophage proliferation, differentiation, and activation, making it indispensable in murine immunology research. This tag-free recombinant mouse Csf2 encompasses the full-length mature sequence (18–141 aa) and demonstrates exceptional signaling potency, with an ED50 below 0.05 ng/ml in FDC-P1 proliferation assays corresponding to a specific activity exceeding 2.0 × 10⁷ IU/mg — providing a reliable basis for cell-based functional assays, JAK/STAT and MAPK signaling pathway studies, bone marrow–derived dendritic cell differentiation, and in vivo models of inflammation or tumor biology. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound myeloid cell activation readouts, while purity greater than 98% by SDS-PAGE supports use as a reference standard in cytokine detection assays and as a positive control for antibody validation by ELISA or Western blot.
