Luminescent spectroscopy of proteins

Description

Luminescent Spectroscopy of Proteins is devoted to the method of intrinsic protein luminescence, one of the most popular experimental methods in modern biophysics and biochemistry. The book discusses general physical principles of the luminescence method; spectral properties of the main protein chromophores; and protein luminescence and its use for studies on structural, physico-chemical, and functional properties of proteins. Principles of luminescent spectroscopy are illustrated by real-life applications and problems. Luminescent Spectroscopy of Proteins will be an excellent reference for biophysicists, biochemists, analytical chemists, and other scientists interested in this topic Content: INTRODUCTION.
