Abstract

The Nelore bull (Bos taurus indicus) seminal plasma proteome was analyzed by MALDI-TOF MS and twodimensional gel electrophoresis. A total of 260 spots were visualized in the 2-DE gel (pI range 3-10) and 13 spots could be identified by peptide mass fingerprinting corresponding to 11 different polypeptides. The results allowed the creation of the first proteomic map of Bos taurus indicus seminal plasma. The roles of the identified proteins in the bull seminal plasma are discussed.
