LANSING, Mich., March 31, 2011 — Neogen has introduced a screening version of its new rapid test for gliadin (gluten) that was developed to better fit the needs of the international testing community.

Alert® for Gliadin R5 is based on the technology behind Neogen’s quantitative Veratox® for Gliadin R5 assay, which was developed to conform to the influential Codex Alimentarius, the global reference point for consumers, food producers and processors, national food control agencies and the international food trade. The new test versions use the Codex Alimentarius recommended “R5” gliadin antibody — the critical test element that “captures” any possible gliadin proteins in a test sample.

“Neogen offers the Alert versions of our food allergen test kits for those who wish to screen only a few samples at a time against a single control level,” said Neogen’s Jennifer Baker. “In validation testing, our new Alert for Gliadin R5 test kit performed comparably to our existing screening test for gliadin, but employs the gliadin antibody recommended by the Codex Alimentarius.”

Alert for Gliadin R5 is intended for the qualitative analysis of in-process ingredients, clean-in-place solutions, environmental surfaces and finished products for the presence of gliadin. The test also features a new proprietary gliadin renaturing cocktail extraction solution that provides consistent results, and does not require the use of a fume hood. Gliadin is a protein found in wheat that belongs to a group of alcohol-soluble proteins called prolamins. Other prolamins include secalin, found in rye, and hordein, found in barley. Gluten consists of two groups of proteins (prolamins and glutelins) that are found in differing amounts in wheat, barley, rye and oats. Gliadin and other prolamins have been identified as major causal agents in a number of disorders, including wheat allergy and gluten intolerance (celiac disease). Wheat allergy is a specific immune response to a number of wheat proteins, including gliadin, albumin, globulin, and glutenin. Celiac disease is a chronic reaction to gluten proteins that results in the poor absorption of nutrients in the small intestine.

Those with celiac disease must avoid gluten, and rely upon the correct labeling of food to make appropriate, safe food choices. Testing for the presence of gluten components ensures food manufacturers that an unlabeled—and potentially dangerous—ingredient did not make its way into a food product.
