Protein Sequence Confirmation with Valens

Protein Sequence Confirmation with Valens

Do you want to confirm the sequence of your protein or antibody sample? We offer sequence confirmation by mass spectrometry using Valens^TM. We’ve successfully confirmed sequences for the following applications:

• Hybridoma verification – Confirm the secreted antibody matches the expected genomic sequence.
• Truncation detection – Identify the translation boundaries and post-translational processing events of your sequence.
• Recombinant protein confirmation – Assess how well the expressed protein matches the intended gene sequence.

Sequence Confirmation Deliverables

• Interactive report with presentation ready images

• Peptide coverage of putative protein

• Per residue confidence score

• Reptor^TM hybridoma sequencing – We provide economical, high-throughput hybridoma sequencing using next-generation sequencing.
• Reptor^TM bulk B-cell receptor sequencing – Complement your hybridoma campaign by sequencing related members of your hybridoma from remaining lymph nodes, spleen, or blood.
• Valens^TM de novo protein sequencing – We determine the full-length sequence of your antibody directly from the protein, no hybridoma needed.

Is your hybridoma monoclonal? Our process can determine the sequence of your secreted protein and confirm it matches to your hybridoma sequence.
