    Antibody Epitope Mapping Service

      Antibody epitopes, also known as antigenic determinants, are the specific structures recognized and bound by an antibody. Accurate identification and analysis of antibody epitopes are crucial in the development of biopharmaceuticals and vaccine design. They not only help in understanding the mechanisms of pathogen infection but also optimize antibody design, enhancing therapeutic effects. Thus, high-precision antibody epitope mapping services are indispensable in advancing modern medical research, offering significant scientific and commercial value for new drug development and vaccine production.


      MtoZ Biolabs employs advanced mass spectrometry technology to offer epitope mapping services. These services enable researchers to accurately identify antibody binding sites on antigens and explore pathogen infection and antibody defense mechanisms thoroughly. With a wealth of experience in experimental design, our team offers strong scientific support for antibody and vaccine research.


      Analysis Workflow

      1. Sample Preparation

      Based on client needs, antibodies and their corresponding antigens are prepared and purified.


      2. Antibody Immobilization

      Antibodies are immobilized on specific carriers to capture their interactions with antigens.


      3. Peptides Digestion

      Antibody-antigen complexes are treated with proteases to release peptides that include the epitopes.


      4. Peptide Analysis

      These peptides are then separated and analyzed using mass spectrometry to pinpoint the epitopes accurately.
