To my knowledge, pUC18 with inserts of 10kb should propagate just fine in
DH5alpha. If the insert is lethal or unstable, the original poster could try
pUC19. I have in the past solved this kind of cloning problems by simply
reversing the insert by using pUC19 instead of pUC18, or Bluescript KS
instead of SK.
