as far as I know the ClaI site is perfectly OK in pBluescript II.
No second site in the vector, no overlapping methylation site,
so - no problem.
Maybe Stratagene wants you to use Bsp106I instead of ClaI, they don't
sell ClaI anymore. I guess they put it in parantheses to show that
it's just an isoschizomer of Bsp106I.
But this is just a guess, if you want to contact Stratagene directly
here's their e-mail address: tech_services at
