Epitope Mapping - CD BioSciences


Epitope Mapping

Epitope Mapping

Epitope mapping is the process of experimentally identifying the binding site (epitope) of an antibody on its target antigen. It is instrumental in antibody drug development and antibody therapeutics.

Dysregulations of signaling transduction pathways usually lead to pathological or disease states. For example,  the mTORC1 pathway regulates many major cellular processes and is implicated in an increasing number of pathological conditions, including cancer, obesity, type 2 diabetes, and neurodegeneration. To find cures for diseases, proteins regulated the relevant pathways are potential targets.

CD BioSciences offers accurate, clear and directly applicable epitope definitions for your antibodies. With us, you can develop potent antibody drugs and protect your drugs with patents.

Epitopes are generally divided into two classes: linear and conformational. Linear epitopes are formed by a continuous sequence of amino acids, while conformational epitopes are discontinuous amino acids brought together upon three-dimensional protein folding.

CD BioSciences offers different epitope mapping methods to suit your need the best. With our advanced technology, we will achieve the timely delivery of the results.

Epitope Mapping

We offer a variety of innovative solutions for in-depth analysis of epitopes for a large range of antibody formats and isotypes, including epitome-wide antibody cross-reactivity analysis, and antigen, epitope and mimotope discovery.


Epitope Mapping
  • Strengthening Intellectual Property (IP).
  • Comparing two antibodies with a similar epitope.
  • Classifying different antibodies into separate binding bins based on discovered epitopes.
  • Identifying essential and variable amino acid positions within an epitope.
  • Understanding of amino acid requirement for a cross-species or multi-strain reactivity analysis.

CD BioSciences offers a comprehensive epitope mapping service package to support your intellectual property (IP) claims, as well as to help you elucidate the mechanisms of binding for antibodies.
