A gel with bad news

I did a mini-prep on some ecoli, and had the result of a previous mini prep. I wanted to see how much DNA I had in each, so I ran a gel with these plus some reference plasmid DNA @ 10ng/ul. Sadly the only bands I saw were for the reference plasmid, so I'm doing something terribly wrong. Cool to see the supercoiled/nicked/linear forms of the plasmid spread apart at least.
