Binding of platinum to human transferrin
Abstract:
A complex of platinum and human transferrin has been formed by appropriately combining apotransferrin (metal free protein) and potassiumchloroplatinate (K2PtCl4). Atomic absorption spectroscopy indicated that both primary bind sites on the protein participated in the complex. Electron paramagnetic resonance (EPR) examination showed that the bound platinum was not paramagnetic, and thus it is highly probable that the Pt ion is in the +2 oxidation state. The results suggest a possible mechanism for physiological distribution of third-transition-series metals.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
