HASGE analysis at pH 7.0 of protein extracts from testis, epididymis, vas deferens and sperm of human and macaque. Equal amounts (60 μg) of protein were loaded in each lane. The large arrow shows a non-staining clear band at ~64 kDa, representing the digested substrate. A narrow band of a much higher MW (approximately 114 kDa) was seen in human caput, human sperm, and macaque corpus, as indicated by the smaller arrow.
