In the Vasopressin Direct RIA, immuno-reactive vasopressin is measured with a double antibody radioimmunoassay according to a modified method of Glick and Kagan. Samples and calibrators are pre-incubated with the anti-vasopressin antibody for 24 hours. 125I-vasopressin then competes with vasopressin present in samples and calibrators for the same antibody binding sites. After a second incubation of 24 hours, the solid-phase second antibody is added to the mixture, and the antibody-bound fraction is precipitated and counted.
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.
