- (RSS) (BioRxiv All) Post-translational modification fidelity of recombinant human lactopontin expressed in Kluyveromyces lactis: Recombinant human lactopontin (rhLPN), an equivalent of human milk lactopontin, is of increasing interest for human nutrition applications due to its roles in mineral binding, gastrointestinal function and immune modulation. These properties depend strongly on post-translational modifications, particularly phosphorylation… https://www.biorxiv.org/content/10.64898/2026.05.12.724256v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
- (RSS) (BioRxiv All) MicrobeMS – A MATLAB Toolbox for Microbial Identification Based on Mass Spectrometry: Over the last two decades, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-ToF MS) has become the standard method for identifying bacteria and has found a wide range of applications, especially in clinical microbiology. The method's high taxonomic resolution, minimal sample preparation, and complete,… https://www.biorxiv.org/content/10.64898/2026.05.08.723807v1?rss=1&utm_source=dlvr.it&utm_medium=mastodon #BioRxiv #MassSpecRSS
