Abstract: A media collection device for retrieving separation media from a container containing the media and organic or inorganic materials is described. The device has a media collecting sieve, support shaft, handle and vibrating source. The device can further have a retainer for the support shaft, a rotating motor, a sliding mechanism, a stage adjustable in height and/or angle, a media receptacle and a container stand adjustable in angle, height and position relative to the stage. Multiple media collection devices can be joined together to simultaneously collect media from multiple containers.

Abstract: The present invention provides a reagent which can be used as a marker to identify individual lanes on an electrophoresis gel which is run on an Automated DNA Sequencer. This reagent is may be included in the loading dye for samples in DNA sequencing, DNA fragment analysis, or linkage mapping analysis. Inclusion of the reagent aids in the identification of the lane in which each sample is individually loaded on the acrylamide gel, such that the data read from each lane by the instrument is correctly applied to the appropriate sample.
