Expression of CpMEDLE-3 in sporozoites and developmental stages of Cryptosporidium parvum. (A) Western blots analysis of native protein from C. parvum sporozoites for CpMEDLE-3, using polyclonal antibodies (left panel), post-immune sera (middle panel) and pre-immune sera (right panel). Lane M: molecular weight markers; lane 1: crude protein extracted from sporozoites; lane 2: purified CpMEDLE-3 protein. (B) Expression of CpMEDLE-3 on C. parvum sporozoites (top panel) and intracellular developmental stages in HCT-8 cell cultures at 24 h (middle panel) and 48 h (bottom panel). The images were taken under differential interference contrast (DIC), with nucleus counter-stained with 4′,6-diamidino-2-phenylindole (DAPI), parasites stained by immunofluorescence with Alexa 594-labled CpMEDLE-3 (CpMEDLE-3), and superimposition of the three images (Merged). Bars = 5 μm.
