The Olsen Group at the Novo Nordisk Foundation Center for Protein Research have unveiled a One-Tip technique that efficiently identifies over 9,000 proteins from a mere ~1,000 cells and an unparalleled 6,000 proteins from a single mouse zygote.
Central to this impressive achievement is the incorporation of our newly released Aurora Elite TS column. This industry-leading, plug-and-play chromatography not only facilitates a streamlined one-pot sample preparation, but when paired with Thermo’s flagship Orbitrap Astral and the Evosep One, produces unmatched and staggering protein IDs.
Beyond the sheer numbers, the One-Tip technique offers a considerable advantage by increasing sample throughput and minimising sample loss. The significance of this research lies not just in its immediate findings, but in its potential to usher in a new era of proteomic studies.Introduction:
Researchers have developed ‘One-Tip’, a groundbreaking lossless proteomics method that radically simplifies the workflow for analyzing protein samples. Traditionally, proteomics required complex multi-step procedures that were not only time-consuming but also prone to errors. One-Tip addresses these issues head-on, streamlining the process without sacrificing depth or accuracy.

Key Highlights:

1. Efficiency:
One-Tip can reliably identify over 9,000 proteins from roughly 1,000 cells and around 6,000 proteins in a single mouse zygote, all at a rate of 40 samples per day.

2. Simplicity:
Contrary to traditional methodologies that demand a myriad of steps, the One-Tip process needs only two pipetting actions and a mere hour of incubation.

3. Accuracy:
The method was tested on varying amounts of HeLa cells, showing impressive proteome depth, even for as few as 20 cells. This is a notable advancement over previous techniques that faced sample losses.

4. Whisper LC Method and Aurora Elite Chromatography:
One-Tip’s superiority in sample preparation pairs well with top-tier LC-MS/MS systems. The combination of the Whisper LC method, used on the EvoSep One LC, and the narrow-window Data Independent Acquisition (DIA) method on Thermo’s flagship orbitrap, the Orbitrap Astral, ensures unparalleled analytical performance. Notably, the integration of IonOpticks’ Aurora Elite chromatography reinforces this setup, making the entire process more efficient and precise.

5. Versatility:
This novel workflow was also applied to study mouse pre-implantation embryos, revealing a more detailed and accurate proteome than previous methods.

Conclusion:
One-Tip stands as a testament to what modern science can achieve when technology and innovation intersect. It paves the way for advanced proteomics research, eliminating the need for intricate methods and specialized equipment during sample preparation. With the inclusion of Aurora Elite chromatography in the mix, researchers can now delve deeper into proteomics with confidence, making scientific discovery faster, more accessible, and incredibly precise.
