hi there,
 the band positions you describe for your gels are caused by a gradient in
buffer components (i.e. formaldehyde diffusing out of gel)... there is a (huge!)
paper in ANALYTICAL BIOCHEMISTRY 94 (probably January or maybe February issue)
discussing the topic and proposing reformulated buffer solutions to alleviate
the problem ...
best wishes for your northern,
