“…One of the main components of gluten, gliadin, which is used as a target analyte in the majority of gluten detection assays contain a number of intramolecular disulfide bonds within its structures. These disulfide bonds should be cleaved for effective extraction of gliadin from a sample and as a reductant 2-mercaptoethanol could serve this purpose [ 21 ]. 2-mercaptoethanol has formerly and extensively been used as a component of gliadin extraction buffers within a variety of gluten detection assays [ [22] , [23] , [24] ].…”
