PF3D7_0930300 merozoite surface protein 1

Parasites were labeled with polyclonal rabbit antibodies to MSP1-19 and secondary antibodies (anti-rabbit Alexa594 to detect MSP1-19 labeling

and anti-mouse Alexa488 to detect internalized MSP2 MAbs, with anti-MSP1-19 at a 1:200 dilution and secondary antibodies at a 1:500 dilution).

Internalized MSP2 MAbs were detected up to 19 h postinvasion. Images are from representative antibodies to the C-terminally conserved region. The labeling of internalized MSP2 MAb was colocalized

with labeling of MSP1-19 by polyclonal rabbit antibodies, further suggesting that MAbs to MSP2 were bound to the parasite surface postinvasion. Lower panel: 3D7 strain merozoites were fixed during invasion for EM and labeled with MSP2 N-terminal antibodies. A repre-sentative image of a merozoite prior to and during invasion is shown. Labeling is indicated with red arrows.
