Rolling Circle Amplification (RCA)

Vadim V. Demidov, Ph.D., is a Senior Analyst in the Biotechnology & Pharmaceuticals Group at Global Prior Art, Inc. (Boston, USA), an intellectual property research and analysis firm. Dr. Demidov received his M.S. degree in Physical and Chemical Engineering from Moscow Institute of Physics and Technology (MIPT, a leading Russian technical university, also known as "the Russian MIT") and his Ph.D. degree in Biophysics from the Institute of Molecular Genetics of the Russian Academy of Sciences (IMGRAS) and MIPT. Before joining the Global Prior Art company in 2008, he worked for almost 30 years in academia and industry worldwide. Dr. Demidov is well known in the molecular biology and biotechnology field for his innovative studies related to peptide nucleic acid (PNA). He has introduced the use of PNA openers for detection of specific sequences within DNA duplexes under non-denaturing conditions, with some of these applications involving rolling circle amplification (RCA).
