Fig. 6From: The mucin-like, secretory type-I transmembrane glycoprotein GP900 in the apicomplexan Cryptosporidium parvum is cleaved in the secretory pathway and likely plays a lubrication roleIFA detection of GP900 protein (green) in invading sporozoites using anti-GP900-C (a) and anti-GP900-N (b) antibodies. F-actin of host cells was stained with phalloidin–rhodamine (red), and nuclei were stained with DAPI (blue)Back to article page
