PfCDPK1 phosphorylated at serine-64 is associated with apical parasite structures. (a) A schizont stage parasite stained with DAPI to reveal the nuclei (blue), an antibody to PfEBA-175 to reveal the micronemes (red) and the phospho-specific CDPK1-pS64 antibody (green). A merge of images from all three stains is shown on the far right; this is a representative image from at least three experiments. Also shown is a rendered image where deconvoluted z stacks were reconstructed in 3D, with interpolation. The inset shows a rendered image of a free merozoite from the same preparation . (b) The same as a, but instead of probing with an anti-EBA-175 antibody the preparation was probed with an antibody to the rhoptry
marker PfTRAMP . Scale bars, a-1 mm (insert-0.5 mm), b-1 mm (insert-0.5 mm).
