Protein Sequencing Service.
REmAb® is our de novo protein sequencing service, using mass spectrometry. REmAb has been unmatched in sequence accuracy, coverage and speed since 2015 thanks to continuous evolution of our protein sequencing technology. Our protein sequencing service determines the amino acid sequence of purified proteins with our proprietary chemistry and AI-powered bioinformatics algorithms.
How REmAb® De Novo Protein Sequencing Works.
The REmAb® de novo protein sequencing workflow delivers a complete protein sequence with unparalleled accuracy and reliability. Starting with just 100μg of purified protein, 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 protein sequence.
Our unique de novo workflow allows us to determine the full protein sequence with hundreds of overlapped peptides without requiring a database or sequence library for reference or homology.

| 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 protein sequencing coverage and confidence in isobaric assignments.
De Novo Sequencing From Any Species.
Our unique de novo workflow allows us to determine the full protein sequence without requiring a protein sequence database or amino acid sequence library for reference or homology.

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”
