title: Diminished quality of two-dimensional (2-D) gel electrophoresis after freezing of the first-dimension gels.
abstract: Two-dimensional (2-D) gels were compared before and after freezing mini isoelectric focusing (IEF) gels in their glass tubes at -20 degrees C. Overnight storage of mini IEF gels significantly reduced the separation, resolution and number of proteins in 2-D gels.
