Anti-Gliadin peptide HYB 314-01 的详细介绍

Cat. No.: HYB 314-01
Product name: Anti-Gliadin peptide
Description: Mouse monoclonal antibody
Specificity: HYB 314-01 reacts strongly with the deamidated peptide but cross-reacts about 5% with the non-deamidated peptide KLQPFPQPQLPYPQPQ.
Immunogen: Gliadin-related peptide Lys57-Glu65-[alpha-gliadin (58-73)] (KLQPFPQPELPYPQPQ)
Application: ELISA, WB
Species reactivity (positive): Wheat, Rye, Barley
Species reactivity (negative): Oat
Subclass: IgG2a/k
Clone number: 14D5
Epitope: The epitope is located in a central region of the Lys57-Glu65-[alpha-gliadin (58-73)] (KLQPFPQPELPYPQPQ) peptide (1).
Content: Available in 200 µL and 1 mL size.1 mg/mL +/- 15%. See Certificate of Analysis for details.
Purification: Protein-A purified
Form: Liquid
Solvent: 0.01 M phosphate buffer, pH 7.4, containing 0.5 M NaCl and 15 mM sodium azide
Storage: 4-8ºC without exposure to light. No precautions necessary during handling.
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 314-01 reacts with both the deamidated peptide (KLQPFPQPELPYPQPQ) and non-deamidated petide (KLQPFPQPQLPYPQPQ) when these are coated directly in an immunoplate, but approx. 20-fold higher concentrations of antibody are needed to produce the same signal with the non-deamidated peptide. (2)
Application 2: WB
HYB 314-01 can be used in western blotting.

A western blot of Gliadin peptide (HYB 314-01) measured in rye (lane 1), barley (lane 2) and wheat (lane 3). The SDS gel was run under reducing conditions, and HYB 314-01 diluted 1:1000.
