A BAC library containing genomic DNA fragments with average size of 163 kb. Generated for physical mapping of the Drosophila genome.
DNA was isolated from adult fly tissue and embedded in agarose blocks. DNA was partially digested with EcoRI and EcoRI methylase, size fractionated and cloned into the pBACe3.6 vector.
A total of 17,540 recombinant clones were initially generated with an average insert size of 163kb (24-fold coverage of the euchromatic portion of the genome)
