Latex beads coated with Mce1D was internalized by HeLa cells. (a) Latex beads coated with mce1D were internalized completely by HeLa cells. (b) Latex beads without protein coating were not observed in HeLa cells. Both solitary beads (arrow) and clusters of beads were present in HeLa cells (some marked by arrows). Bars = 2 μm.
