Existance of a Bovine Sperm Antibody Recognizable Antigen-Epitope on the Plasma Surface of Lily Sperm Cells

Chen Zhong-ying, Zhu Guang-lian and Tsao T H (Cao Zong-xun)   

Abstract: By using Western blot and rabbit-anti-bovine sperm IgG as the first antibody, a 64 kD protein from sperm cells of Lilium davidii Duch. and the same molecular weight protein from generative cells of L. davidii as well as a 22 kD and a 65 kD protein from sperm cells of Zea mays could be detected. Nevertheless, proteins from filament and anther wall of L. daviclii or etiolated shoot of corn manifested negative reaction. By indirect immunofluorescence assay using the same antibody, the surface of sperm cells from L. daviclii showed positive reaction. Based on the results, the authors believed that a plant sperm cell might have the same epitope (s) as that of an animal sperm cell; the epitope (s) might locate on the surface of a sperm cell and be specific to sperm cells.
