Sterile cell culture plate
The invention responds to the need to observe under transmission electron microscope (TEM) the cell morphology just observed at the inverted light microscope. The device allows to culture the cells on the same support that will be used for subsequent microscopic analysis. This allows to obtain top quality images at high magnification and high resolution without altering the cell morphology under examination.
One of the methods used to observe the cells culture in TEM implies the use of chemical, enzymatic and/or mechanical treatments to detach the cells from the plastic of the culture plate. These approaches result in the loss of both the specific area of interest observed under light microscope and the specific morphological aspects assumed by the cells as a consequence of eventual experimental treatments.
The patented system is a plate with removable bottom consisting of multiple wells. The plate enables the cells cultivation in vitro and in sterility, and the processing and inclusion of the cells in resin for further TEM analysis directly on the same plate. After resin polymerization and removal of the culture well’s bottom the embedded cellular sample is immediately ready to be cut into observable sections.
