Characterization of an Eppin Protein Complex from Human Semen and Spermatozoa1

14 Jun 2007

Abstract excerpt

Eppin (SPINLW1; serine peptidase inhibitor-like with Kunitz and WAP domains 1 (eppin); epididymal protease inhibitor) coats the surface of human ejaculate spermatozoa and originates from Sertoli and epididymal epithelial cells. In this study, we have isolated native eppin from ejaculate supernatants (seminal plasma) and washed ejaculate spermatozoa using column chromatography and two-dimensional SDS-PAGE, and...
