Fig. 3From: 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 roleWestern blot detection of native GP900 protein in the crude extracts of oocysts using affinity-purified anti-GP900-C polyclonal antibody (a) and anti-GP900-N monoclonal antibody (b). Note that the band recognized by each antibody was above the upper most band (250 kDa) in molecular markers (M)Back to article page
