The Anti-Transglutaminase Antibodies ELISA is intended for the quantitative measurement of anti-transglutaminase antibodies in stool samples. This ELISA is one of twelve that utilizes a single stool extraction procedure for a multi-analyte gastroenterology panel. Research Use Only. Not for Use in Diagnostic Procedures.

This ELISA is used for the quantitative determination of anti-human tissue transglutaminase (antihtTG) sIgA antibodies in stool. In a first incubation step, the anti-htTG sIgA antibodies in the sample are bound to their antigen (human recombinant transglutaminase), which is immobilized to the surface of the microtiter plates. To remove all unbound foreign substances, a washing step is carried out. In a second incubation step, a peroxidase-labeled anti-sIgA antibody is added. After another washing step, to remove all unbound antibodies, the solid phase is incubated with the substrate, tetramethylbenzidine. An acidic stop solution is then added to stop the reaction. The color converts from blue to yellow. The intensity of the yellow color is directly proportional to the amount of bound anti-tTG antibodies and can be determined photometrically at 450 nm. The sample results are evaluated by comparison with a cut-off value.
1. What percentage of your IgE allergy testing panel consists of molecular allergens rather than allergen extracts? The ALEX2 IgE allergen panel consists of 117 extracts and 183 molecular allergens. This represents the largest panel of molecular allergens on the market, including 50 unique...
Cases of food and environmental allergies have been increasing over the last decade. While conservative estimates suggest IgE-mediated allergy affects 6-8% of children and 2-3% of adults, some estimates are as high as 30%.3, 2 Symptoms can range from mild to severe and include itching, hives,...
Food sensitivity or food intolerance involves a non-allergic response to a food or food additive. In a recent on-line survey conducted in the U.S., 24% of adults aged 18 to 79 reported a food intolerance. While a food allergy is typically mediated by IgE antibodies, adverse reactions to food...
