Protein Sequence Confirmation Service

Are you unsure if your protein sample really is what you think it is? We can help!

Sequence confirmation is a distinct process from our Valens™ de novo protein sequencing service. In sequence confirmation, we have a putative sequence against which to verify the sample. We provide a probability of each amino acid being correct. Read below on different applications of Valens™!

Get started on your project.

Applications of Valens™

Hybridoma Verification

  • Sequence confirmation is a distinct process from de novo sequencing to confirm the translated protein product matches your genetic sequence.

Truncation Detection

  • Identify the translation boundaries and post-translational processing events of your sequence. 

Recombinant Protein Confirmation

  • Access how well the expressed protein matches the intended gene sequence.

 Antibody Protein Sequencing Service

Our antibody protein sequencing service can determine the primary amino acid sequence of your monoclonal antibody directly from the protein. Using mass spectrometry together with our patented spectral networking approach, Valens™ recovers full-length amino acid for heavy and light chains.
