REmAb® de novo Antibody Sequencing by Mass Spectrometry.
Our antibody sequencing service determines the amino acid sequence of monoclonal antibodies with our proprietary high-throughput, full coverage de novo antibody sequencing technology.
How REmAb® de novo Antibody Sequencing Works.
How It Works.
The REmAb® de novo antibody sequencing workflow delivers the complete antibody sequence, including CDRs, with unparalleled accuracy and reliability. Starting with just 100μg of purified antibody, the sample undergoes multi-enzyme digestions and the fragments are measured with LC-MS/MS to derive the de novo peptide sequences. These fragments are then analyzed by Rapid Novor’s suite of bioinformatics algorithms to assemble the full-length antibody sequences of any isotype.
Our unique de novo workflow allows us to determine the full antibody sequence with hundreds of overlapped peptides without requiring a database or sequence library for reference or homology.

| REmAb® | Others | |
|---|---|---|
| Throughput | 50 to 100 mAbs per week | Single runs |
| Accuracy | 100% | Often low / ambiguous |
| Sample volume requirement | 50 μg (as low as 7μg) | >150 μg |
| Multi-enzyme digest | At least 5 – 10 enzymes | 1 or 2 |
| Bioinformatics software | Proprietary, next generation algorithms | Previous generation commercial software |
| Accurate Ile/Leu Determination | Yes, WILD® and WILDtag technology | Rarely |
| Ability to handle the unexpected | Yes: additional chains, impurities, oligos, etc. | Rarely |
| Depth of coverage | 100X | Low or patchy |
| Downstream impact | One sequence that works, every time | Costly ambiguities to express and test |
WILD® Isoleucine-Leucine Determination.
Isobaric combinations with confidence: our patented WILD® method was the first commercial service to use additional peptide fragmentation via electron transfer high collision energy dissociation (EThcD) to create and analyze w-ions. This enables true Isoleucine-Leucine determination based on experimental evidence alone. Our unique and patented WILDtag chemistry increases coverage and confidence in isobaric assignments.
De novo Sequencing of Any Isotype from any Species.
Our unique de novo workflow allows us to determine the full antibody sequence without requiring a database or sequence library for reference or homology. We’ve worked with all isotypes and popular constructs, including bispecific, chimeric antibodies, nanobodies and fAbs. Secure 100% coverage of variable domains and obtain antibody sequences that recognize the right antigen with de novo sequencing service.

Success Stories.
100% of respondents were happy with the experience
Respondents were 9.7/10 likely to refer their peers.
85% were already successful downstream. Remainder were in progress. No reported failure.
“You are certainly the best CRO we’ve ever worked with!❤️”
“We’ve focused on coupling cytokines with highly engineered VHVL of an antibody. So by sequencing the antibodies with Rapid Novor we are able to pull out the CDR to grant them into our platform and test in vitro and in vivo”
“Rapid Novor was tasked with finding highly specific, high affinity antibodies against an important target – and they delivered powerful antibodies fit-for-purpose. Such antibodies are not easily obtained yet Rapid Novor approach proved immediately successful, despite our time-constrained and stringent demands”
