Magic ferritin: A novel chemotherapeutic encapsulation bullet

The dissociation of apoferritin into subunits at pH 2 followed by its reformation at pH 7.4 in the presence of doxorubicin-HCl gives rise to a solution containing five doxorubicin-HCl molecules trapped within the apoferritin. This is the first report showing that ferritin can encapsulate an anti-cancer drug into its cavity.
