Centers for microscopy and imaging include multi-photon fluorescence microscopy, confocal microscopy, computational optical sectioning microscopy, and scanning and transmission electron microscopy (including cryo-EM). Mass spectrometry and X-ray crystallography facilities are available at Washington University and the Danforth Plant Science Center to facilitate studies of protein structure and function. Modern greenhouses, growth chambers, and tissue culture facilities provide controlled environments for plant research. The Washington University library system has access to virtually every major journal in the biological and chemical sciences. The facilities of the Missouri Botanical Garden, which include a botanical library and herbarium collection that are among the most extensive in the world, are also available to all students.
