Figure 2. Binding of rNV VLPs to human gastroduodenal tissue and inhibition by human milk.
Tissue sections from the gastroduodenal junction of a secretor (A, C and D) and a non-secretor (B) were incubated with rNV VLPs and the binding was detected as described in the Materials and methods section. In (C, D) VLPs were co-incubated with milk samples from secretor and non-secretor women respectively, at a dilution of 1:10. All pictures taken are from the pyloric area. A complete absence of VLP binding was observed in the presence of milk from a secretor, as in the tissue from a non-secretor.
