[Bioluminescence and bioluminescent analysis: development of certain aspects of the problem over the last decade].

Recent data from gene engineering, kinetic and fluorescent studies concerning the structure and functions of firefly luciferase are reviewed. Some new trends in the development of bioluminescent methods of control over bacterial contaminations, dynamics of intracellular processes and methods of bioluminescent detection in immuno- and DNA-assays are described. Possible applications of luciferase genes as markers are considered.
