Smile! Proteomics sample preparation simplified

Fast, reliable, standardized methods for sample preparation ready for  mass spectrometry analysis

The challenge:

Complex, multi-step methods of proteomics sample preparation for mass spectrometry analysis have inherent challenges of time, contamination and sample loss. Preparing labelled samples over an extended time period with a complex method leads to variation in results. This challenge is exacerbated with large numbers of samples and small starting amount of input material.

The solution:

PreOmics improved sample technology enables robust and reproducible sample preparation. The iST method provides significant time savings as complex workflows previously requiring many different reagents taking 48 hours are replaced by a single kit containing all standardized reagents. The iST kit allows proteomics sample preparation for mass spectrometry analysis, whether manually, semi or fully automated on the PreON, in a 2 hour time window.

Apply! Simple, streamlined workflows

Samples should be liquid, homogenates or a soft pellet.
Lyse, reduce, alkylate
Add LYSE reagent, incubate for 10 mins at 95°C.
Cool, add DIGEST reagent, incubate for 60 mins at 37°C.
Load onto cartridge, WASH and ELUTE. Dry and resuspend in LOAD.
MS analysis
Inject and analyse to see improved peptide identities.
For technical data and performance statistics see the iST Application note

Time flies with PreOmics iST sample preparation

While standard proteomics sample preparation takes around 44 hours – the same time as flying around the world non-stop, PreOmics kits take the same time as flying from our Munich HQ to London or from Boston to Chicago.  

Increase your sample throughput, improve quality and produce reliable data.
