Scal amp resistance gene

[John Sargeant]

Dear Net, does anyone have or know of a pUC derivative that does NOT
have a ScaI site in the ampicillin resistance gene.  For example has
someone gone to the trouble of using site directed mutagenesis to remove
it.  I would like to use a clone like this to get myself out of a
difficult cloning corner.

Mike
