Patent ID: 8426145

Claim:
A method for diagnosing Celiac Sprue in an individual, said method comprising detecting the presence of a multivalent oligopeptide selected from the group consisting of (SEQ ID NO:12) LQLQPFPQPQLPYPQPQLPYPQPQLPYPQPQPF or a deamidated counterpart thereof; and a gluten oligopeptide or a deamidated counterpart thereof, having the formula: E 1 -X 1 -E 2 -X 2 -E 3 . . . X n -E y , wherein E 1 , E 2 and E 3 are independently selected T cell recognition epitopes that, when contained in a peptide, can stimulate T cell proliferation in an individual with Celiac Sprue, X 1 and X 2 are independently selected from the group consisting of a peptide bond and at least one amino acid, n=1-5, and y=0-5, in a tissue, bodily fluid, or stool of said individual.
