Abstract
Ferric ions show high affinity to the kinase-generated phosphorylated sites of peptides. Thus, the high electrocatalytic activity of the coordinated ferric ions toward the reduction of hydrogen peroxide can be used for sensitive label-free monitoring of protein kinase activity and inhibition.
摘要
