Abstract

Methods and systems for detecting allergens using mass spectrometry are provided herein. In some aspects, a sample can be screened for the presence or quantity of ovalbumin, lysozyme, casein (isoform S1 and S2), lactoglobulin, high and low glutens, wheat, rye, oats, barley, mustard, sesame, and various types of nuts including macadamia, pistachio, brazil, walnuts, peanuts and hazelnuts by detecting one or more peptides specific to the allergen of interest using selected MRM transitions.

Description

technical field [0001] The present invention generally relates to kits and methods for the detection and quantification of allergens in samples, such as food samples, using mass spectrometry. Background technique [0002] Food allergies can induce deleterious immune responses such as dermatitis, asthma, gastrointestinal injury, anaphylactic shock, etc. Conventional methods for detecting and / or quantifying allergens in food samples typically employ immunoassays, which can have a number of disadvantages. For example, one such method called enzyme-linked immunosorbent assay (ELISA) requires the use of expensive kits and is at best semi-quantitative. In addition, conventional immunoassays are generally limited to a single allergen per screen and frequently result in false positives due to lack of specificity. [0003] Accordingly, there is a need in the art for improved kits and methods for the detection and quantification of allergens in food samples. Contents of the invent...
