Distribution of Sp17 in human spermatozoa. Western blot demonstrating that Sp17 is present in both the soluble fraction (S) and the pellet (P) fraction of the CHAPS extract of human spermatozoa. As reported previously [4], the pellet fraction, which contains the majority of the Sp17 present in the lysate, has two groups of immunoreactive proteins, 22–24 kDa and 19–20 kDa (arrows).
