Hi Jesse,

I prefer the targetted approach.

I made a series of PCR fragments where I could control where the fragment

breeze. Make a t-vector version of your reporter construct and clone in your
pcr fragment.


p.s. I performed this for 5' and 3' deletions .....would have used an
exonucleoase III method but did not have any appropriate enzyme sites to use
such a method
