Utilization of seminal proteins by house gecko, Hemidactylus brooki(Gray), sperm for motility.

ABSTRACT

Five protein fractions of medium electrophoretic mobility were observed in the seminal plasma of H. brooki. On incubation of sperm in phosphate buffered saline and Zn and Mg free buffer, both containing seminal plasma, two of the protein fractions disappeared while a third fraction had become weak. The results suggest that H. brooki sperm utilize seminal proteins for motility.
