Abstract
The present invention includes a novel method and system for identification of microorganisms in samples that proteins and other biological material from non-microorganism sources (e.g., proteins of mammalian origin) that can interfere with identification of the microorganisms. The methods and systems described herein include use of a single-use chromatography medium to purify intact proteins prior to mass spectrometry analysis. The chromatography medium and the methods described herein can rapidly and efficiently remove of a substantial portion of interfering biological material (e.g., mammalian proteins) from a crude cell lysate while preserving high signal strength and removing enough of the interfering protein(s) to allow for identification of the microorganism(s) by mass spectrometry analysis.
