摘要

<正> Human sperm membrane antigens extracted by deoxycholate （DOC） were used to immunizeBALB/c mice.Hybrid cell lines secreting sperm-specific monoclonal antibodies were generatedby cell fusion in a semi-solid medium and screened by indirect immunofluorescent assay usinglive and methanol-fixed sperm.Out of 850 hybrid clones from cell fusion

28 were shownto secrete sperm-specific antibodies which reacted with the acrosome

equatorial segment

whole surface plasma membrane or tail of spermatozoa.Finally

seven hybrid cell lineswere established and shown to secrete monoclonal antibodies which had no cross-reactivitywith arty human tissues other than testis and sperm.The majority were also shown toinhibit fertilization of mouse oocytes in vitro and human sperm penetration of zona-freehamster ova.Western blot analysis revealed that some of these antibodies reacted withsperm membrane antigens of distinct molecular size.
