Serotransferrin mediates iron delivery to proliferating cells through receptor-mediated endocytosis, making its functional integrity essential for studies of metal homeostasis and cell growth regulation. This full-length mature protein (residues 20–698) demonstrates robust biological activity in serum-free proliferation assays with MDCK cells, yielding an ED50 of 0.5–2 μg/mL—a quantitative benchmark that confirms preserved iron-binding and receptor-engagement capacity. The validated mitogenic response supports use in ligand-binding and cargo-release assays, membrane transporter functional studies, and drug-protein binding experiments where transferrin serves as a physiological carrier model. Produced in mammalian cells without affinity tags, the protein exceeds 95% purity by SDS-PAGE and maintains endotoxin levels ≤0.5 EU/mg, meeting the quality thresholds commonly required for cell-based assays and biophysical characterization where contaminants could obscure receptor interactions or conformational measurements.
