There are many monoclonal antibodies for which the hybridoma cell line is unavailable. To complement our hybridoma sequencing service, we are also offering a de novo antibody protein sequencing service.
By combining mass-spectrometry with high-accuracy de novo peptide sequencing and assembly of overlapping peptides, the amino acid sequences of the variable domains are determined.
We guarantee to deliver a functional antibody sequence along with a comprehensive sequencing report with full sequence coverage. In combination with our transient expression service, we

De novo sequencing workflow: The antibody is digested using multiple enzymes. On each digest LC-MS-MS is performed and peptides predicted de novo. Using proprietary software, overlapping peptides are assembled into a full coverage protein sequence.
can sequence an antibody and deliver recombinant versions in as little as 9 weeks.
The whole combined service is priced at 13,600 GBP / 17,500 USD / 15,300 EUR. For more information please contact us.
