Observations from the proteomics bench - Quality Assessment / Experiment Reproducibility - EXIII2023


ABSTRACT: These project contains 10 technical replicate measurements of a standard sample, that is used to assess the quality control and instrument performance in between real project samples. It was used in a viewpoint paper to illustrate the challenges. The samples were measured with three different machines, one is given in this project, two other projects for the other machines exist.

INSTRUMENT(S): Orbitrap Exploris 480

ORGANISM(S): Homo Sapiens (human)

TISSUE(S): Epithelial Cell Of Lung, Alveolar Epithelial Cell Line

Many challenges in proteomics result from the high-throughput nature of the experiments. This paper first presents pre-analytical problems, which still occur, although the call for standardization in omics has been ongoing for many years. This article also discusses aspects that affect bioinformatic analysis based on three sets of reference data measured with different orbitrap instruments. Despite continuous advances in mass spectrometer technology as well as analysis software, data-set-wise qu  ...[more]
