Expression and localization of apoA1 and prom1 in murine sperm. Immunoblots of proteins from cauda epididymal sperm confirmed that apoA1 and prom1 were expressed at the appropriate molecular weights (A). ApoA1 was transferred to the sperm plasma membrane during epididymal transit (B–I), consistent with the results of immunoblots for this protein (C). However, localization of prom1 was conserved between different epididymal regions, showing the midpiece and the cytoplasmic droplet (arrows) (B–II).
