Mapping of 1400 expressed sequence tags in the bovine genome using a somatic cell hybrid panel.
A bovine/hamster hybrid cell panel consisting of 30 independent hybrids was developed to locate genes. Polymerase chain reaction analysis of 279 microsatellites on the cattle linkage map in this panel revealed the presence of all chromosomes in either entire or fragmented form. Among primer pairs prepared from bovine 3'-expressed sequence tags (ESTs), 1400 ESTs were assigned to specific chromosomes, of which 1303 were newly assigned in this study, and mapped 854 (61%) to 1 of 192 chromosomal segments using this panel. The regional mapping of new genes to cattle chromosomes can be rapidly achieved using this panel.
