How will epitope data help you?


What makes our epitope mapping platform better?

We have mapped 1,000+ epitopes to date with >95% success, including:
- Epitopes on GPCRs, transporters, and viral envelope proteins
- Conformational epitopes
- Epitopes on multi-subunit proteins
- Receptor state-dependent epitopes
"The epitope mapping that Integral Molecular has done has greatly supported both our mechanistic understanding and the intellectual property claims of our proprietary antibodies."
-HEAD OF IMMUNO-ONCOLOGY, BIOTECH COMPANYHow do we achieve a >95% success rate?

Shotgun Mutagenesis Epitope Mapping:
- Automated point mutation of every residue in the target protein to alanine
- Native expression of each protein mutant in human cells
- Native expression of individual mutants in human cells, enabling mapping of conformational epitopes
- High-throughput expression, antibody reactivity, and functional testing
- 3D structural visualization of the epitope
What epitope mapping services do we offer?
Antibody Epitope Mapping Services
An Ala-scan mutation library is created for the protein target of interest and used to test binding of customer’s MAbs/ligands by flow cytometry to identify epitope residues
See examples of our services: Mapping on the fusion protein of RSV for Merck Mapping of CXCR4 nanobodies for Ablynx
Expedited ReadyMap Epitope Mapping Services
Expedited epitope mapping is available on full-length, pre-constructed and pre-validated ReadyMap libraries for quicker lead selection
ReadyMap Oncology Libraries:
HER2, HER3, PD-L1
Additional ReadyMap libraries launching soon
Mapping Small Molecule Binding Sites
Small molecules are screened on the library using functional assays to identify amino acid residues that are critical for binding or function
See examples of small molecule mapping: Mapping on GPCR TAS2R16 Mapping on GPCR CXCR4
Epitope Mapping Projects Include:
- Assay Setup Report, summarizing optimized conditions for screening
- MAb/ligand screening on the Ala-scan mutation array
- Final report, containing:
- 1. Fully analyzed data package
- 2. Identification of amino-acid resolution epitope
- 3. Publication-ready figures
120+ Epitope Mapping Publications & Patents
"Integral Molecular was able to identify critical binding residues for an antibody for which no mapping had been successfully done after years in development."
"Excellent team, excellent communication, results when promised, results with impact to drive decision making."
