Epitope Mapping Service

What is Epitope Mapping

Epitope Mapping is the process of identifying epitope, the binding site of an antibody to a target antigen.

Epitope mapping, providing specific amino-acid sequence bound with antibody, is essential element

of developing monoclonal antibody for diagnosis and treatment.

GeneOnBioTech provide world class epitope mapping

based on ‘175,000 Peptide array’


The number of peptide in peptide array used in Epitope Mapping

Epitope Mapping service of other company use 5,500~20,000 peptides.

Epitope Mapping service of GeneOnBioTech uses 175,000 peptides for more accurate and broad result.

You can receive higher resolution result

which you cannot get from other Epitope Mapping Service.


There are two type of antibody epitope, Linear epitope and Conformational epitope.
They are named after their characters, continuous epitope and Discontinuous epitope.

Because most of other peptide array realize linear form only,

It was hard to identify antibody binding with Conformational epitope.

Our 175,000 peptide array, realized in 3D structure, can identify antigen with discontinuous epitope.

Outline of research service of Epitope Mapping

○ Identify Sample-Peptide Interaction through peptide array experiment

○ Select Top-ranked Interaction depended on A-score

○ Verify selected 3D structure/conformational form

○ (Optional) If antigen is suggested, perform sequence comparison between the antigen and experimentally confirmed peptides.


Gene On Peptide array : < 175,000 peptides of < 15-amino acids

GeneOnBioTech provides world-class level peptide array research service.

GeneOn Epitope Mapping Research/Analysis Service

You can receive Raw data and Research results report through GeneOnBioTech’s Epitope Mapping Research/Analysis service.

○ Raw data

Raw data of 100,000 Peptide accumulated as a double spots.

○ Data analysis
(Example of Data analysis)
Derivation of results through data analysis(Repeatedly detected peptide sequence identification).
