Thanks to everyone who replied to my plea for help with this puzzling
(at least to me :-) ) problem. The solution was, as many pointed out,
that the EtBr in the gel and the running buffer was not enough to stain
such a huge amount of DNA, and thus all the EtBr got soaked up by
the lower bands so I could not see the higher molecular band anymore.
A second try with staining after the gel run showed the right band, 
and so I can happily go on with further experiments.

Thanks ...
