Hi there, I am planning to make a BAC library from a plant species
starting with sheared genomic DNA or partially restricted genomic DNA.
There is also a company (Epicentre) which provide a kit (pWEB cosmid
cloning kit) to make libraries of large genomic inserts (~40 kb)
starting from sheared DNA , but it does not seem to be very popular.
I have no idea how difficult it is to make such libraries and what kind
of problem can hinder the success in making this kind of libraries.
