Identification of Unambiguous Borrelia Peptides in Human Urine Using Affinity Capture and Mass Spectrometry

Methods Mol Biol. 2024:2742:105-122. doi: 10.1007/978-1-0716-3561-2_9.

Abstract

The combination of advanced mass spectrometry and enrichment-based sample preparation methods has enhanced analytical capabilities in clinical proteomics. In this chapter, we describe a method of proteome analysis to identify Borrelia-derived peptides in urine that includes a sample affinity enrichment method coupled with liquid chromatography tandem mass spectrometry analysis and a bioinformatic peptide authentication algorithm.

Keywords: Affinity capture; Borrelia; Direct test; Mass spectrometry; Polyamide; Sudan IV; Sudan black B; Urine.
