Description:
A monoclonal antibody to an antigen in the human germ cell membrane did not agglutinate or immobilize sperm but inhibited binding and penetration of zona-free hamster ova by human sperm and blocked murine fertilization in vitro. The antibody, of the 2a subclass of immunoglobulin G, was germ cell-specific but not species-specific. It recognized a single antigen of 23 kilodaltons that has been isolated from human germ cells. This fertilization antigen, located on the postacrosome , midpiece, and tail of human sperm, is a glycoprotein of testicular origin associated with some types of human involuntary immunoinfertility .〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Naz, R K -- Alexander, N J -- Isahakia, M -- Hamilton, M S -- HD-14572/HD/NICHD NIH HHS/ -- HD-16608/HD/NICHD NIH HHS/ -- RR-00163/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1984 Jul 20;225(4659):342-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6539947" target="_blank"〉PubMed〈/a〉
