Smile! Protein and peptide sample preparation automated

Applications for Agilent Bravo

The challenge:

How do you bring further standardization, reproducibility and hands on time savings to proteomics sample preparation for LC-MS analysis when you have already successfully addressed the many challenges of time, sample contamination, sample loss and reproducibility?

The solution:

In conjunction with Agilent, PreOmics®' kits are suitable for use on the Agilent Bravo platform. Meeting the demands of reproducible, robust and sensitive proteomics sample preparation for LC-MS analysis, these applications allow research labs to partially automate proteomics processing, decreasing the hands on time.

Apply! Simple, streamlined workflows

1. Adding samples

Samples should be liquid, homogenates or a soft pellet.

2. iST kit setup

Add the appropriate iST kit components to Agilent Bravo.

3. Sample preparation

Protocols need to be programmed by an in-house specialist.

4. MS analysis

Inject samples into your LC-MS system.

5. Data analysis

Process your data to see improved peptide identities.

The partially automated Agilent Bravo requires off-board centrifugation. The figures above show data generated on the Agilent Bravo in a partially-automated protocol, using 1 µL plasma with analysis on a Thermo Q-Exactive HF Orbitrap.
