timsTOF Pro - The new standard for shotgun proteomics

Powered by PASEF

Mass spectrometry (MS)-based proteomics has become a powerful technology for the identification and quantification of thousands of proteins. However, the coverage of complete proteomes is still very challenging due to the limited speed, sensitivity and resolution of current mass spectrometers.

The timsTOF Pro uses the Parallel Accumulation Serial Fragmentation (PASEF) acquisition method to provide extremely high speed and sensitivity to reach new depths in shotgun proteomics and phosphoproteomics using low sample amounts.

Achieve near 100% duty cycle for shotgun proteomics

A near 100% duty cycle for high sensitivity, high speed shotgun proteomics can now be achieved with the dual TIMS technology. The novel design allows for ions to be accumulated in the front section, while ions in the rear section are simultaneously released depending on their ion mobility. This process is called Parallel Accumulation Serial Fragmentation or PASEF.

MaxQuant/Perseus and PEAKS Studio enabled data processing

An open-file data format allows researchers to directly work with the raw data and use industry leading software. MaxQuant has been adapted to manage 4D features in the space spanned by retention time, ion mobility, mass, and signal intensity which benefit the identification and quantification of peptides, proteins, and posttranslational modifications. PEAKS Studio combines de novo sequencing with tradtional databbase searches and is optimized for processing timsTOF raw data.

PASEF digs deeper into the proteome

The timsTOF Pro powered by PASEF offers sequencing speed > 100 Hz without losing sensitivity by synchronizing the quadrupole isolation mass window with the elution time of the specific peptide packages from the TIMS funnel.

"We now know that the peptide mixtures are still extremely complex when analyzing them in two dimensions (retention time and m/z). Adding one more dimension should in principle get us a long way ahead. In addition to the additional dimension of separation, the timsTOF Pro gives us extremely high speed and sensitivity to get deeper into the proteome and using less sample material.”
