A database was developed to store, organize, and retrieve the data associat
ed with electrophoresis and chromatography separations. It allows laborator
ies to store extensive data on separation techniques (analytical and prepar
ative). The data for gel electrophoresis includes gel composition, staining
methods, electric fields, analysis, and samples loaded. The database store
s data on chromatography conditions, the samples used and the fractions col
lected. The data structure of this database was designed to maintain the li
nk between samples (including fractions) from chromatography separations an
d their analysis by gel electrophoresis. The database will allow laboratori
es to organize and maintain a large amount of separation and sample data in
a uniform data environment. If will facilitate the retrieval of the separa
tion history of important samples and the separation conditions used.
