It increases the growth of numerous cell types including hybridoma and primary cell lines. The optimal concentration for cell culture differ with the cell line. The reported effective concentrations for hybridoma and vero cell lines range from 5 to 20 mg/L. Effective concentrations for primary cells range between 5 to 100 mg/L.

One mg of of the protein can bind to approximately micrograms of Fe. Recommended stock concentrations are 5 to 20 mg/ml in PBS, though others can be used as well. Avoid the formation of bubbles when dissolving the protein.
