Description
G-CSF (CSF3) is a critical regulator of granulopoiesis, and this tag-free recombinant form covering the full mature sequence (residues 31–204) demonstrates exceptional signaling potency, with an ED50 below 0.1 ng/ml in NFS-60 cell proliferation assays corresponding to a specific activity exceeding 1.0 × 10⁷ IU/mg. This level of bioactivity supports use in neutrophil differentiation and myeloid progenitor expansion assays, JAK/STAT3 and MAPK signaling pathway studies, and as a reference standard for G-CSF detection in ELISA or multiplex cytokine panels. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound immune cell functional readouts, making this preparation appropriate for sensitive in vivo models of infection or myelosuppression recovery. Produced in *E. coli* at greater than 98% purity by SDS-PAGE, the protein also provides a suitable basis for antibody development workflows including immunization, coating antigen use, and Western blot positive controls.
