Blocked Xba I sites?

I'm trying to characterize some mouse genomic clones and
one of the enzymes I've been using is Xba I.  I know that
some Xba I sites are blocked by methylation if the DNA
is maintained in bacteria that are not dam(-).  But are Xba I
sites ever blocked in eukaryotic DNA?  

Thanks in advance.
