title: Immunoglobulins and monoclonal anti-blastocyst antibodies in the mouse uterine secretion during the early pre-implantation period.
abstract: A Sepharose bead blot technique was used to study immunoglobulins in the uterine secretion of mice during the pre-implantation stage. Secretion collected by Sepharose beads contained IgA, IgG, and IgM. The method could be made ten-fold more sensitive by using anti-mouse IgG or IgM conjugated to Sepharose beads. It has also been demonstrated that when injected intravenously, biotinylated purified immunoglobulins, both non-specific mouse myeloma IgG and IgM and specific anti-blastocyst IgG and IgM, is able to pass into the uterine cavity of the mouse. It was further shown that when injected systemically, anti-blastocyst antibodies can reach the blastocyst. Functionally active specific antibodies against morulae and/or blastocysts may, therefore, be able to influence the pre- and peri-implantation development of the embryo and could serve as a useful model for experiments directed towards the identification of immunological contraceptive procedures.
