This ELISA is used for quantitative determination of hemoglobin/haptoglobin complex in stool. The complex in the sample is bound to anti-haptoglobin antibodies (in excess), which are immobilized on the surface of the microtiter wells. To remove all unbound substances, a washing step is carried out. In a second incubation step, an anti-hemoglobin peroxidase-labeled antibody is added. After another washing step, to remove all unbound substances, the solid phase is incubated with the substrate, tetramethylbenzidine (TMB). An acidic 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 concentration of hemoglobin/haptoglobin complex in the sample. A standard curve is generated with the values obtained from the standard (optical density vs. concentration). The presence of hemoglobin/haptoglobin complex is determined directly from this curve.
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...
The ALPCO Glucagon ELISA is for the quantitative determination of glucagon in human EDTA plasma. This assay was developed for ease-of-use and demonstrates superior sensitivity while eliminating cross-reactivity issues present in other commercially-available assays.
ALPCO’s automated turbidimetric solution for calprotectin testing offers enhanced efficiency without compromising clinical sensitivity or specificity. Clinicians can prioritize endoscopic evaluation for the patients that need it most and quickly put IBS patients on the right treatment path.
Join our speaker from Department of Pathology , University of Utah School of Medicine, Dr. Heather Nelson, to discuss how to validate and launch a FDA-approved assay.
