Monoclonal antibody from vasectomized mouse identifies a conserved testis-specific antigen TSA70.

Vasectomy results in the occlusion of testicular outflow, leading to autoimmunity characterized by the production of antisperm antibodies (ASA). Reports on the rise in ASA following vasectomy in several species are available; however, not much is known about the specific sperm autoantigens to which postvasectomy antibodies are directed. In the present study, monoclonal antibodies were generated using a vasectomized mouse.

Monoclonal antibodies to epididymis-specific proteins using mice rendered immune tolerant to testicular proteins.

Monoclonal antibodies (mabs) have been used as a powerful tool for identification of newer sperm proteins. However, conventional hybridoma technology rarely provides chance to obtain mabs to epididymal proteins. To increase this chance, we have used an alternate method of neonatal tolerization.
