Generation of a P1 artificial chromosome library of the Southern pufferfish

We describe the generation of a P1 artificial chromosome genomic library fr om the Southern pufferfish, Spheroides nephelus. The arrayed library consis ts of similar to 30,000 clones and has an average insert size of 125-150 kb . The coverage is estimated to encompass seven to eight genome equivalents. The library has been used for isolating numerous genomic clones and for es tablishing contigs of several multigene families. Analysis of several of th e clones from this library suggests a preponderance of CA re eat tracts rel ative to their abundance in humans. The library and high-density filters ha ve been made available to the scientific public through genomics distributi on companies. (C) 2001 Published by Elsevier Science B.V. All rights reserv ed.
