Smile! Biological fluid sample preparation simplified

Fast, reliable, reproducible sample preparation minimizing artificial modifications

The challenge:

The multi-step methods of protein sample preparation for mass spectrometry analysis have inherent challenges of time, contamination and sample loss. When preparing biological fluids (e.g. plasma and serum) for proteomic analyses, harsh reagents may introduce artificial modifications resulting in reduced protein and peptide identifications.

The solution:

PreOmics®’ iST-BCT sample preparation kit was developed to enable the robust processing of biological fluids and has been optimized to minimize artificial modifications (e.g. deamidation, oxidation) and increase the alkylation rate. Complex workflows previously requiring many different reagents over a two day time period are replaced by a single kit containing all standardized reagents to accomplish preparation for mass spectrometry protein analysis whether manually, semi or fully automated on the PreON in a 2 hour time window.

Apply! Simple, streamlined workflows

1. Samples
Samples should be liquid, homogenates, or soft pellets.
2. Lyse, reduce, alkylate
Add LYSE reagent, and incubate for 10 mins at 95°C.
3. Digest
Cool, add DIGEST reagent, and incubate for 60 mins at 37°C.
4. Purify
Load onto the cartridge, WASH, and ELUTE. Dry and resuspend in LOAD.
5. MS analysis
Inject and analyze to see improved peptide identities.


Time flies with PreOmics® iST-BCT sample preparation

While standard proteomics sample preparation takes up to 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!
