    Target

    Celiac disease is associated with a CD4+ T-cell response to epitopes of gliadin presented by HLA-DQ2 or -DQ8 class II MHC molecules. These epitopes are present in a 33-mer peptide of wheat alpha-gliadin, residues 56-88, which is resistant to digestion and forms a substrate for tissue transglutaminase (TG2), generating the glutamic acid residues essential for binding to HLA-DQ2. The immunogen corresponds to a deamidated form of a region that includes the T-cell epitopes, including the immunodominant PQPQLPY region and two PXPQP motifs associated with binding to IgA from patients with celiac disease. Complete homology exists between residues 63-73, 70-80 and 77-87 of wheat alpha gliadin.

    Application 1

    ELISA
    HYB 314-02 reacts equally strong with both the deamidated peptide (KLQPFPQPELPYPQPQ) and the non-deamidated peptide (KLQPFPQPQLPYPQPQ) when coated directly in an immunoplate (1). HYB 314-02 is also usefull as a detection antibody in combination with a polyclonal anti-Gliadin capture antibody (2, 3).

    Application 2

    WB
    HYB 314-02 can be used in western blot.
     

    A western blot of Gliadin peptide (HYB 314-02) measured in wheat (lane 1) and barley (lane 2). The SDS gel was run under reducing conditions and HYB 314-02 diluted 1:4000.
