Protocols and Applications


Investigating the increased lifespan in C. elegans daf-2 mutants by 4D-Lipidomics™

The small nematode Caenorhabditis elegans is one of the premier biomedical model organisms and employed in many aspects of basic and applied science.... More


Next-generation MALDI top-down sequencing of protein biotherapeutics – expanding the scope of timsTOF technology

This new method takes advantage of Trapped Ion Mobility Spectrometry (TIMS), to further enhance MALDI-TDS by adding another dimension of separation in the gas phase.High confidence N- and C-terminal sequencing specifically are enhanced by combining high resolution (~ 60,000 RP) and 2 ppm mass accura...

Achieving Reproducible and Automated Region-Specific Lipid Annotations using CCS-aware SpatialOMx®

The CCS-aware SpatialOMx® workflow opens new dimensions by combining the molecular and spatial information measured by MALDI-TIMS Imaging with highly confident 4D-Omics annotations. MetaboScape® 2021b and SCiLS™ Lab 2021a provide the interface to match data from both ionization techniques and enable... More


How to Determine Glycan Profiles of Biopharmaceuticals from Peptide Mapping Data

Glycosylation is a common critical quality attribute (CQA) of therapeutic proteins and needs to be characterized during product development. Typically, this analysis is conducted after enzymatic release and tagging of the glycans followed by fluorescence and MS detection. However, that approach lose... More


High throughput 4D-Proteomics – Application of dia-PASEF® and the Evosep One for short gradients

In this application note, we demonstrate the benefits of dia-PASEF technology on the timsTOF Pro platform coupled to an Evosep One for high-throughput in-depth proteome analysis of up to 300 samples per day (SPD). We quantify about 5200 protein groups in only 21-minutes run time. In 4.8-minutes ultr... More
