Following protein kinase acivity by electrochemical means and contact angle measurements.
The electrochemical analysis of the protein kinase, casein kinase, is accomplished by the voltammetric response of Ag(+) ions associated with the phosphorylated product; the sensing surface is regenerated by the cleavage of the phosphorylated product with alkaline phosphatase, and the phosphorylation/de-phosphorylation processes are monitored by XPS and contact angle measurements.
