Smile! Phosphoproteomics sample preparation simplified

Fast, reliable, reproducible sample preparation for phosphoproteomics workflows

The challenge:

Phosphoproteomics sample preparation methods for mass spectrometry analysis have inherent challenges of time, contamination and sample loss. Preparing labelled samples over extended period with a complex method leads to variation in results. This challenge is exacerbated when high starting protein concentrations are needed to acheive detection limits and when in combination with enrichment techniques and with sample throughput requirements.

The solution:

PreOmics improved sample technology,  iST-Phospho sample preparation, allows streamlined enrichment of phosphopeptides and an efficient peptide clean-up step. The iST-Phospho method decreases hands-on time and minimises sample loss. Complex workflows previously requiring many different reagents over a XXXXX time period are replaced by a single kit containing all standardised reagents to accomplish phosphoproteomics  preparation for mass spectrometry  protein analysis whether manually, semi or fully automated in a XX  hour time window.

Apply! Simple, streamlined workflows

Lyse, reduce, alkylate
Samples should be liquid, homogenates or a soft pellet. Add LYSE reagent, incubate for 10 mins at 95°C.
Cool, add DIGEST reagent, incubate for 60 mins at 37°C.
Phospho enrichment

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. 

It’s as easy as i-S-T!
