The TGF-β1 ELISA is an enzyme immunoassay for the quantitative in vitro diagnostic measurement of TGF-β1 in serum and cell culture supernatant. FDA Registered. For In Vitro Diagnostic Use.
Transforming Growth Factor β1 (TGF-β1) is a 25 kDa homodimer composed of two 12.5 kDasubunits joined by disulfide bonds (1). TGF-β1 is a multipotent cytokine with cell- and dosedependent activities. This molecule is produced by a number of cells and tissue types, e.g.thrombocytes, bone tissue, placenta and kidneys. This potent cytokine modulates embryonicdevelopment, bone formation, mammary development, wound healing, hematopoiesis, cell cycleprogression and the production of the extracellular matrix. With respect to the immune system,TGF-β1 inhibits T and B cell proliferation and acts as an anti-inflammatory molecule both in vitroand in vivo. TGF-β1 inhibits macrophage maturation and activation. This molecule also inhibitsthe activity of natural killer cells and lymphokine activated killer cells and blocks cytokineproduction.
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.
