Invitro mutagenesis

When I was a graduate student, I did a lot of mutagenesis via the Kunkle
method.  It was generally very successful, but I did have one mutant I
wanted to make that just never worked with that method.  In the end, I used
a PCR-based approach.  I'm sure you could find such methodologies described
in detail in something like "Current Protocols in Molecular Biology" or
even someplace on the web.  I've had very good success using PCR to do site
directed mutagenesis.  In fact, this is about the only way I do it now.
