Confocal Microscopy and Image Analysis Group
Head of the Group

Grigory I. STEIN

Leading Scientist, Ph.D.

phone: (812) 297-13-13

The Group was organized in 2002 to investigate scientific and methodological problems of confocal microscopy and image analysis, also to help researchers of Institute in their microscopic studies. Now the Group has laser scanning confocal microscopes OlLYMPUS FV3000, LEICA TCS SP5, fluorescent microscopes AXIOVERT 200M, AXIOPHOT and AXIOSKOP with digital videosystems.
