timsTOF HT

The new timsTOF HT mass spectrometer is equipped with the 4th generation high capacity TIMS-XR analyzer and advanced digitizer technology (ADT). It offers higher dynamic range for unmatched analytical depth and quantitation in high-throughput proteomics experiments. The timsTOF HT is fully CCS-enabled and supports all PASEF^® acquisition modes including PASEF^®, dia-PASEF^® and prm-PASEF^® achieving flexibility in 4D-Proteomics™. Simply uncompromised proteomic depth at scale.

We recognize the inherent duality of research investments: opportunity and risk. Embracing innovation's dynamism, we prioritize upgradable research platforms. This commitment fosters sustainability and empowers researchers to navigate the ever-evolving landscape.

Our upgradable platform seamlessly integrates the latest advancements, keeping your projects at the forefront of discovery. It grants researchers the flexibility to choose the optimal moment to leverage these advancements, maximizing the impact of their work and aligning perfectly with their research goals.

Maximize your identification depth and throughput with the new capabilities of Bruker ProteoScape™, our “run and done” database search platform. TIMScore™ and TIMS DIA-NN take full advantage of the CCS for more accurate protein identification on the fly.

The timsTOF platform stands out for its exceptional reliability and minimal maintenance needs, making it ideally suited for seamless integration into everyday laboratory workflows with maximum uptime and fast turnarounds. More than >7000 protein groups can be identified on average in only 5-minute gradient time with ease and across sites. Achieve top edge reproducibility over time without manual interference.

Rapid cardiac tissue proteomics. Different amounts of a murine heart proteome digest were analyzed in triplicates with short liquid chromatography gradients and dia-PASEF^®. At the highest sample load, we identified in total 4700 protein groups spanning more than five orders of magnitude in relative abundance. Raw data were processed with DIA-NN in library-free mode and protein copy numbers were estimated with the ‘proteomic ruler’ approach.  

For even higher proteome depth, increased protein digest loads improve identifications. A tryptic digest of human cell line K562 (Promega) was analyzed using a nanoElute^® system at 250 nL/min with 60 min separation time on an Aurora column (25cm, 75 μm ID, IonOpticks). timsTOF HT operated in dia-PASEF^® mode using 100 ms TIMS separations. Data was processed with TIMS DIA-NN using a predicted library from uniprot (human reviewed).

We combined the use of a PQ500 (Biognosys) Stable Isotopic Standard (SIS) with a dia-PASEF^® based appoach using a 30 min gradient on a timsTOF HT.  578 proteins (corresponding to 804 peptides) could be accurately quantified with a > 99% data completeness. This approach combines the selectivity and sensitivity of traditional SMS/MRM methods with an easy-to use acquisition setup, also allowing to define new targets a posteriori.

A) The TIMS-XR allows for increased ion capacity for sample loads beyond 200 ng. Reproducible identification of ~ 6900 protein groups and more than 86,000 unique peptides.

B) Number of identifications using the Bruker ProteoScape™ realtime search engine with TIMScore™ for dda-PASEF of up to 1600 ng K562 tryptic digest. Error bars indicate standard deviation for 5 replicates with mean displayed above histogram.

Using a PepSep™ Twenty-five series column (150 μm ID, 1.5 μm particle size), average peak of widths less than five seconds were achieved for K562 tryptic digest (Promega) sample loads up to 1600 ng. A gradient time of 41 min was adequate for efficient peptide separation, resulting in homogenous peptide elution across the gradient even at high peptide loads.
