Fig. 3From: Novel avian single-chain fragment variable (scFv) targets dietary gluten and related natural grain prolamins, toxic entities of celiac diseaseSchematic view of scFv fragment cloned into the expression vector pET28a (+). VH and VL fragments assemble to full-length scFv in between the linker peptide and are ligated into pET28a (+) vector, which provides a C-terminal hexahistidine tagBack to article page
