Souther blot and restriction mapping

Hi all, I would greatly appreciate any help with constructing a restriction map from Southern Hybridisation data. I can construct restriction maps from fragment data obtained through endonuclease digestion and separation by standard gel electrophoresis, ...

Restrction digest on a plasmid--how many fragments?

You are right. In a multiple cloning site, the restriction site are usually within less than20 to 30 bp of one another. Look at ... so for n plasmid you have at best 2n molecule of EtBr linked to your short fragment and someting like 500n or 1000n in the plasmid. When you adjust the sensitivity ...
