There's a hole in my assay, dear ELISA, dear ELISA! Using targeted MS to detect gluten in beer that is invisible to ELISA.

摘要

ELISA is suitable for measuring gluten in raw, unprocessed food precursors, such as flour. In beers, the presence of gluten fragments leads to suppression of the ELISA response. Targeted mass spectrometry holds promise as an alternative to the WHO-accepted ELISA technology.
