Jakob Willforss of the Department of Immunotechnology was, following a public vote, awarded a poster prize at 'Proteomic Forum 2019' which recently took place in Potsdam, Germany. He presented a poster entitled 'Evaluation of peptide quantification susceptibility for technical bias from batch effects and batch compensation'. In this study he evaluated how the impact of mass-spectrometry specific batch effects vary for peptides with different characteristics. The aim is to provide a metric of batch stability, which would help guiding the identification of stable biomarkers and ultimately help to develop batch correction algorithms that also consider the unique characteristics of mass-spectrometry based data.
