Immunoblot analysis of TEKT2BP1 in spermatozoa. Rat spermatozoa from caput and cauda epididymis were purified by Percoll-density gradient centrifugation, and purified spermatozoa were lysed by RIPA buffer. Both extracted (Super) and undissolved proteins (Pellet) were processed for SDS-PAGE. Separated proteins were either stained with Coomassie brilliant blue (A) or transferred to PVDF membrane for immunoblot analysis using the antibody against TEKT2BP1 (B). A protein migrating at approximately 36 kDa was detected in the supernatants of both caput and cauda spermatozoa. No band was detected in the undissolved samples (pellet). Molecular masses of the standard proteins are shown in the left in kilo-Daltons.
