Alkaline phosphatase problem...

Hi There:

A unique problem has surfaced in our lab and I was wondering if anyone else has
had a similar experience.  When using alkaline phosphatase to remove 5'
phosphates from cloning vectors, has anyone ever had the problem of having the
alkaline phosphatase treatment digest one's vector as well?  Various reagents
have been changed, water, Tris, ZnCl2, the enzyme, all to no avail.  Does
anyone have any suggestions or comments?  

Thanks in advance...
