Abstract
Abstract A multi-mode apparatus for capturing light patterns emitted or absorbed by a planar sample, such as an electropheresis gel, is made possible by a unique tray and sample holder system which positions a sample at a pre-determined focal plane of the solid state camera integral to the apparatus. Each sample is fixed in a sample holder specific to the mode of labeling of the sample. The tray is configured to retain each sample holder at a different elevation with respect to the side walls of the tray for proper placement of the sample at the focal plane. The tray side walls are adapted to position a sample holder at the proper elevation depending on the sampling mode and illumination technique selected. The sample holder includes a combination of transparent, translucent, or opaque plates designed to allow illumination and imaging of the sample for the particular labeling method employed.
