Immunoelectron micrographs of extracellular merozoites of P. falciparum. Merozoites were incubated with (A) mouse antiserum to bacterial lysates of clone C7, (B) mouse antiserum raised to E. coli containing the cloning vector pUC8 (negative control). Hsp70 is localized at the surface of the merozoite. The location of p75 on the merozoite surface is unusual for an hsp-related protein, as most of these are normally intracellular.
