A BAC library containing genomic DNA fragments 75 to 150 kb in size. Generated for physical mapping of the Drosophila genome.
DNA was isolated from embryos, then partially digested with either NdeII or HindIII, and cloned into the pBeloBAC11 vector.
A total of 23,400 clones were initially generated. Clones with a "BACN" prefix were prepared with NdeII, and those with a "BACH" prefix with HindIII.
