Valens Overview

 

Antibody Protein Analysis with Valens™

Direct protein analysis is critical to antibody characterization, including determining the primary amino acid sequence and any post-translational modifications that are present.  Valens™ is a mass spectrometry-powered service to provide direct information about the antibody protein.  We offer two services using Valens™; antibody protein sequencing to recover the full antibody sequence when no source cell is available and antibody sequence confirmation to determine if the produced antibody matches the intended gene sequence.

 

Check out our recent blog post that summarizes when to use these de novo antibody sequencing services.

Valens software analysis

Valens™ builds upon two patented technologies developed at the University of California – San Diego.

Valens™ uses the patented spectral networking paradigm, which proposes that any single mass spectrum contains incomplete information and interpreting many spectra in concert results in higher antibody sequencing accuracy. We’ve seen the principles of spectral networking in action for nearly 10 years. The approach allows us to recover the sequence of antibodies from any species and any level of divergence from the germline.

For antibody sequence confirmation, Valens uses the generating function approach to score mass spectrum matches to protein sequences.
