Application note: Quantifying gluten in beer using an ASBC-approved ELISA method

With the recent rise in the prevalence of celiac disease, monitoring gluten levels in food and beverage has become increasingly important as more people strive to avoid gluten.

FDA guidelines specify that foods labeled ‘gluten-free,’ ‘no gluten,’ ‘free of gluten,’ or ‘without gluten’ must contain less than 20 parts per million (ppm) of gluten. This is the limit of quantitation (LOQ) for currently accepted test methods.

In this application note, Molecular Devices measured the gluten levels in six commercially available beers using the RIDASCREEN Gliadin competitive ELISA. The ELISA assay was read on the SpectraMax® ABS Plus Microplate Reader and analyzed using SoftMax® Pro Software.
