Peptide Mapping

Peptide maps that detail the entire protein (100% sequence coverage) are required to prove molecular structure as well as determine post-translational modifications (PTMs) and sequence variants. Complex protein digests (from monoclonal antibodies (mAbs), antibody-drug conjugates (ADCs) and bi-specifics) require high peak capacity, high-resolution separations, and reliable detection combined with confident data analysis.

Discover a peptide mapping workflow solution that includes fast, reproducible protein digestion and comprehensive peptide identification software, with Thermo Scientific™ Vanquish Flex™ UHPLC systems and the Thermo Scientific™ Q Exactive™ BioPharma platform at its heart.

Peptide Mapping Workflow

"Peptide mapping is easy", said no scientist, ever. The typical challenges that face anyone undertaking a peptide mapping experiment would be the amount of time and effort that it takes, from the numerous in-solution tryptic digest steps, through to the variability in digestions leading to an overall lack of reproducibility, and the difficulty in interpreting complex results. Thankfully, we’ve looked at these challenges and are challenging the status quo that peptide mapping is complex!

Benefits

SMART digest kits allow you to obtain high quality analytical results from protein digests as they provide fast and simple protein digestion with high reproducibility, high sensitivity, and high levels of data quality in a format that's compatible with automation. The SMART Digest Kits are a significant improvement over current in-solution protein digestion technologies, which are not reproducible, have poor sensitivity, and employ protracted methodologies not amenable to automation.



SMART Time Savings

SMART vs. traditional digest: there’s no competition.

Use our Digestion Time Calculator to see how quickly the SMART Digest Kit can digest proteins for your application.

SMART Technology

Unlike traditional digestion which requires reduction and alkylation to enable complete digestion, SMART heat denatures the protein, ensuring it is in its unfolded state.

The imobilized trypsin can be present in excess, meaning significantly reduced digestion times and also a cleaner final sample with no trypsin autolysis peptides, reduction or alkylating agents present.


Reproducibly SMART

You can have analytical technologies that provide all the reproducibility and accuracy that you require, but if your sample preparation cannot deliver reproducibility then you could be setting up to fail from the start.

User-to-user, lab-to-lab, SMART takes the worry out of sample preparation and allows you to focus your efforts elsewhere.
