The protein composition of cells depends on the cells’ function and current condition. Mass spectrometry (MS) can determine the identity and quantity of the proteins found in a sample. However, the data analysis of this method is time- and resource-intensive. Researchers at the Max Planck Institute of Biochemistry (MPIB) have collaborated with data science specialists from Verily in the USA to develop a machine learning approach – continuously self-improving algorithms – to facilitate the analysis of mass spectrometry data. Their results, which simplify MS applications and also led to the discovery of new chemical patterns in proteins, are published in the journal Nature Methods.
