Abstract

Botulinum neurotoxin (BoNT) is well known for causing the lethal disease botulism. The only widely accepted test for the identification of BoNTs in both clinical specimens and food is the mouse bioassay. In this study, we use MALDI chips functionalized by biotin-binding protein neutravidin prepared by ambient soft ion landing at atmospheric pressure for enrichment and detection of biotinylated peptides – products of specific endoproteinase activity of BoNT/A. The functionality of surfaces modified with biotin-binding molecules could help to drive the MALDI-TOF mass spectrometry toward its implementation into routine clinical practice.
