Listed are the distributions of BAC clones that are mapped to each of the eight chromosomes. All the mapped clones are anchored to an STS marker. Additional information on each mapped clone is available on our database, GenMapDB, http://genomics.med.upenn.edu/genmapdb. Single colony cultures of all the mapped BAC clones are available through Research Genetics (Huntsville, AL).
