Hi Brian,
I routinely use Klenow to remmove the 3`overhang. All I do is to add the
enzyme directly to the restriction digest without any dNTP. In absence of
any nucleotide ( incubate 10 min at RT) the enzyme removes the 3`overhang
and may be little bit more. Then I add the dNTPs and incubate further 15
min to obtain a blunt end.
Cheers, Kamal.
