Gluten detection kits Simple ● Specific ● Sensitive Emport, LLC for Biomedal SL
What is gluten detection? “Gluten� refers to the storage proteins in certain grains. Gluten is composed of several different types of protein, for example wheat contains several different types of gliadins and glutenins.
Antibody
33-mer peptide
Different gluten detection kits use different antibodies to identify components of gluten. However, most components of gluten are actually safe for people with celiac disease! Research indicates that a only very small fraction is toxic for celiacs: the 33-mer peptide of the Îą-gliadin molecule. The G12 antibody in all GlutenTox kits was specifically developed to detect this toxic peptide. G12 searches for the QPQLPY sequence, found only in the 33-mer peptide. Because of this specificity, G12 is a superior choice for fermented, hydrolyzed, or heattreated foods with complicated molecular structures.
G12, Celiac Disease and Oats Q: Are oats gluten-free? A: Sometimes. Oats are often subject to cross contamination (in the field and/or during processing). However, just because oats have been grown and processed carefully does not mean they are gluten-free. A 2010 study showed that some oats contain gluten. Different strains have different avenin structures, and some are toxic to celiacs. The study used the G12 antibody to review several strains of pure oats: • 3 distinct groups of oat were identified by G12 ELISA: no, low and high toxicity strains. • When the oats were introduced to cells from celiac patients, the cells responded appropriately: they only reacted to the toxic oat strains. Accordingly, G12 is the only antibody proven to detect toxicity in oats and the best choice for any company working with gluten-free oats.
The G12 antibody recognizes the 33-mer peptide, which is present only in the α- gliadin protein and which triggers a celiac response. α-gliadin molecule V

Uses of The GlutenTox line of products is an easy, cost-effective way to: Check surfaces in cases of accidental cross-contamination Spot-check and quantify incoming ingredients, batches of product, surfaces, etc. Confirm that ingredients are safe (A 2010 study published by the American Dietetic Association found that 30% of inherently gluten-free grains found in the supermarket had more than 20ppm gluten (corn flour, rice, millet, etc.); Verify that sauces/soups/large-batch items are safe for gluten-free diners Spot-checking dishes to ensure that staff is appropriately trained in allergenfree preparation We want using GlutenTox to be as easy as possible, and will work with you to develop a program that meets your needs.

FAQs Q: Are test results valid sooner than 10 minutes / after more than 10 minutes? A: If the sample has a high concentration of gluten, a pink line may appear in only a few minutes. This is a valid result. However, if no pink line appears you must wait the full 10 minutes to declare a truly gluten-free sample. Test results may shift if left out for too long (positive results fade in intensity and negative results sometimes develop a faint pink positive line), so it’s important to check promptly at 10 minutes. Q: Can you show me some studies? A:
• Gut journal study showing how G12 works with oat • Stanford University study explaining the 33-mer peptide • Stanford University, University of Seville and Biomedal study explaining the G12 and related A1 antibodies • American Dietetic Association study of inherently gluten-free grains
FAQs Q: Why is the kit not recommended for chocolate? A: Gluten from chocolate or cocoa is very hard to extract because of the phenols present in this matrix: they can chelate gluten. For this reason the level of gluten can be slightly underestimated. However, if you get a positive result with chocolate, it definitely does contain gluten and should not be consumed by celiac disease patients.
Chocolate
is a Sticks kit with a special extraction buffer specifically developed to test cacao or chocolate.
Q: Can the kit be used with fermented, hydrolyzed or baked goods ? A: Yes, the G12 antibody specifically recognizes the fragment that is toxic to celiac patients and can therefore assess toxicity even if the food is fermented, hydrolyzed or heat processed.
FAQs Q: Why is it important to shake the sample vigorously in the extraction stage? A: This stage is crucial because it breaks apart the sample so that the gluten molecules can be isolated / detected. The first step is to grind and homogenize the sample as much as possible. The second step is to shake it, which continues the grinding/breaking-down process. If you need to stop briefly during the 2 minutes of shaking, itâ&#x20AC;&#x2122;s OK. Just make sure the total amount of shaking time is at least 2 minutes.
Q: What do I do with the test once Iâ&#x20AC;&#x2122;ve used it? A: All elements of all GlutenTox tests can be disposed of in ordinary trash, or recycled where appropriate.
FAQs Q: Do I need to purchase separate swabs for surface testing? A: Nope! The test strip is all you need. Youâ&#x20AC;&#x2122;ll notice that when the strip is faceup, one end has a fuzzy, cotton texture. This end is what gets rubbed directly onto the surface you are testing, and it is also what gets inserted into the dilution solution. One thing to be careful of: always surface test using clean hands (or a glove), to ensure that you do not accidentally contaminate the strip. Q: Can I use GlutenTox Home to surface test? A: We recommend using GlutenTox Pro or GlutenTox Sticks, however in a pinch you can modify GlutenTox Home to surface test. Simply pry open the plastic casing with a thin blade and remove the test strip. You can then treat it like any other surface test.
