Smile! High throughput sample preparation simplified
Fast, reliable, standardized methods for bottom-up proteomic sample preparation on positive pressure devices
As LC-MS instrumentation has developed, there is a growing need to increase sample throughput and sample preparation can become the rate-limiting step.
The PreOmics iST-PSI workflow couples the simplicity of the iST technology with positive pressure plate processing. Positive pressure processing is known to improve recovery and reproducibility compared to negative pressure or centrifugation. The format is easily automated on major liquid handling platforms including Tecan Resolvex A200 and Hamilton [MP]2.
Apply! Simple, streamlined workflows
Samples should be liquid, homogenates or a soft pellet.
2. Lyse, reduce, alkylate
Add LYSE reagent, incubate for 10 mins at 95°C.
Cool, add DIGEST reagent, incubate for 60 mins at 37°C.
4. Processing on positive pressure device
Load onto SPE plate. WASH and ELUTE on positive pressure device. Dry and resuspend in LOAD.
5. MS analysis
Inject and analyze to see improved peptide identities.

Time flies with PreOmics iST-PSI 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.
