If you look really carefully, you can see a band in between the two. Now that band may be unligated plasmid. I don't really know what else it could be. The bottom band is definitely 1.1kb anchor. The top band could very well be ligation product. It is inconclusive because in my haste I did not run a ladder. But I will gel extract and test anyways. Let's hope upon hopes. I will also run the ligation tomorrow with the rest of my digested pBR322 (20ul left).
