Human and camel lactoferrin, were labeled with technetium-99m using a simple technique that yielded a labelling efficiency of 98% and stable complexes over time. The camel Lactoferrin was purified. The proteins were investigated for targeting infections in experimental animals. The biodistribution of those labeled proteins in mice infected with Staphylococcus aureus at the femoral muscle was investigated and test ratios of 3.43 and 3.71 were obtained after 60 min for the camel and the human Lactoferrin, respectively. These values were compared to each other and to those reported in the literature, leading us to conclude that the radiotracers are efficient.
