Instrument Standardization and Quality Control
As the
Director of the McGill University Life Sciences Complex Imaging Facility we
are developing protocols and standards for testing the quality of light
microscopes. We have developed protocols for measuring laser stability,
microscope alignment, resolution, and objective lens quality. We are leading
world wide studies on instrument quality and publishing detailed protocols
enabling microscopists world-wide to validate and maintain their equipment.
These tests are applied routinely to all of the microscopes within the
facility ensuring researchers are working on top performing equipment.
Imaging Facility
The facility has
13 state-of-the art light microscopy platforms used by ~150 users from
60 laboratories across Montreal to conduct their microscopy based
research. The facility has expertise in many areas including live cell
imaging, total internal reflection fluorescence (TIRF) microscopy,
fluorescence lifetime imaging microscopy (FLIM), multi-photon
microscopy, laser micro-dissection, fluorescence correlation
spectroscopy (FCS), image processing and analysis, spectral imaging and
high content screening. We have also developed and run more than 30
workshops and courses, in collaboration with corporations in the field
of light microscopy, including the inaugural Montreal Light Microscopy
Course (MLMC) in 2010. We are busy planning MLMC 2012 for July 9-20,
2012.
