Tth 111 II

[Laurence T. Reiter]

So I was doing this restriction mapping on some sequence which I just got and
I found the perfect enzyme which would be most informative on a Southern of 
genomic DNA.  The computer cheerfully belched out: Tth 111 II!  What?  Yup.
Tth 111 II is so special a restriction enzyme, in fact, that it is not 
commercially available.  THUS:

HELP!  Does anyone out there know where I can get Tth 111 II?

Thanks,
