“…Because CD patients rely on correct labeling to identify safe products, it is essential that a high degree of confidence can be placed into a gluten-free claim. However, this degree of confidence is, in part, dependent on the characteristics of the assay used to determine the gluten content (Thompson and Mendez 2008), because of the aforementioned divergence of results between different ELISA test kits.…”

“…One major drawback of this assay is that measure-ments of this subfraction with the extrapolation to total gliadin have theoretical errors of -44 to +80% [108]. Moreover it is unable to accurately detect and quantify barley prolamins and cannot accurately quantify hydrolyzed gluten [109].…”

“…This test uses the R5 monoclonal antibody directed to the potentially celiac toxic epitope QQPFP (glutamine-glutamine-proline-phenylalaline-proline) present in wheat, rye, and barley prolamins. This immunoassay is able to quantify native and heated gluten although it seems to overestimate barley hordein [113] and to be unable to accurately quantify hydrolyzed gluten [109].…”

“…W analizie tej wykorzystano monoklonalne przeciwciało R5, które rozpoznaje toksyczne sekwencje aminokwasów (epitopy) QQPFP, QQQFP, LQPFP i QLPFP w gliadynie pszenicy i w odpowiadającym jej białkom glutenowym zawartym w jęczmieniu (hordeinie) i życie (sekalinie). Mimo że przeciwciało R5 nie wykazuje reaktywności krzyżowej z białkiem owsa, to jednak awenina zawierającą sekwencję QQQPF może także z nim przereagować [28,29]. Do pomiaru parametrów tekstury muffin (profil tekstury, twardość i sprężystość) używano analizatora tekstury TA.XT Plus (Stable Micro Systems, Wielka Brytania).…”
