Distribution of Glycoproteins on Feline Testicular Sperm, Epididymal Sperm and Ejaculated Sperm

Journal of Veterinary Medical Science, 2011
Glycoproteins (GPs) are known to be involved in the phenomenon of sperm maturation and capacitation. In the present study, we investigated the attachment of GPs on sperm cell membrane during the process of feline sperm maturation from testicular sperm to ejaculated sperm by using 8 FITC-labeled lectins.
