Distribution of spermatozoa in the outer perivitelline layer from above the germinal disc of emu and ostrich eggs
To whom correspondence should be addressed. email: [email protected] Abstract In the present study, we determined the distribution of spermatozoa in the perivitelline layer above the germinal disc (GD) of emu and ostrich eggs that had been laid at random intervals after mating. Eggs were opened, the perivitelline layer overlying the GD region was collected and…Read More
Amino acid sequences and phosphorylation sites of emu and rhea eggshell C-type lectin-like proteins.
Avian calcified eggshell layers contain in their organic matrix one or two C-type lectin-like proteins. Previously characterized eggshell proteins of this family are chicken ovocleidin-17 (OC-17), goose ansocalcin and ostrich struthiocalcins 1 and 2 (SCA-1, SCA-2). In this report we present the amino acid sequences of two emu (Dromaius novaehollandiae) (dromaiocalcin-1 and -2; DCA-1, DCA-2)…Read More
