HYB 314-01-02 detects the Gliadin peptide in wheat samples. 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. It reacts specifically with the deamidated peptide when coated directly in an immunoplate.
NOTE: Concentration is lot-dependent and can vary from 0.85-1.15 mg/mL
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. Complete homology exists between residues 63-73, 70-80 and 77-87 of wheat alpha gliadin.
