Polyclonal Antibody Sequencing.
Use REpAb® polyclonal antibody sequencing to convert your pAb to a set of mAbs. Get the robust performance of your polyclonal antibody and the reliability of recombinant antibodies, by sequencing the antibodies within the pAb and recombinantly expressing the dominant form(s).
How Polyclonal Antibody Sequencing Works.
Through proprietary chemistry, separation, sample preparation and artificial intelligence, hundreds of mass spectrometry experiments come together to derive the full sequences of mAbs within a polyclonal mixture. The workflow involves multiple enzymes and uses bottom-up, top-down and middle-down mass spectrometry. AI-powered de novo sequencing and assembly algorithms are used to overlay the enormous data set to determine the full antibody sequences.

Unique Technology for pAb Sequencing.
REpAb is the only commercial polyclonal antibody de novo protein sequencing platform – we are uniquely capable of sequencing antibodies from a complex polyclonal mixture without reference to a sequence database or genomic information.
Applications of Polyclonal Antibody Sequencing.
As a stand-alone service, polyclonal antibody sequencing is most commonly used in development of in-vitro diagnostics (IVD). IVD that are based on pAbs are highly dependent on the producing animal, and are subject to costly revalidation and batch-to-batch variability. Converting them to rmAbs leads reduces supply chain risk, and eliminates revalidation concerns. REpAb can also be used for antibody discovery.
Antibody Sequencing Success Stories.
“You are certainly the best CRO we’ve ever worked with!❤️”
“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”
Getting Started With Polyclonal Antibody Sequencing.
Requirements
- 1 mg polyclonal antibody – must be antigen-affinity and protein A/G purified IgG
- Most species (rabbit, chicken, goat, sheep, camelid, dog, etc.)
- Single host (not pooled); pooling from multiple bleeds of a single host is acceptable
- Optional: 100 μg antigen protein
- Optional: NGS data or PBMCs from the same host at a similar time point
Deliverables
- Full length heavy and light chains
- Chain pairing, including any alternate pairs observed
- Ranking (based on confidence/abundance)
- Coverage maps
Monoclonal or Oligoclonal Antibody Sequencing
REmAb® is our other sequencing service, designed for the simpler problem of sequencing monoclonal proteins. It can also handle multiple chains or oligoclonal mixtures of a handful of antibodies. Learn about REmAb Antibody Sequencing Service.
Antibody Discovery
REpAb® polyclonal sequencing technology can be used in an antibody discovery context, starting from antigen synthesis or immunization, and carrying through to pre-clinical development. Please see our Antibody Discovery Service page for details.
