MoBiTec GmbH Teams Up with Protobios to Offer Epitope Mapping Service Using Mimotope Variation Analysis (MVA) Technology

A drop of human blood is presumed to have 10e11 specific antibodies that recognize different immunogens (natural antigen epitopes and antigenic mimics, mimotopes). Although the potential size of the human immunoglobulin repertoire has been estimated, the understanding of its overall involvement in the immune response has remained elusive, mainly because researchers are not yet able to decipher it. MVA technology has overcome that problem. Protobios' novel technology platform, Mimotope Variation Analysis (MVA, patent pending), for parallel and quantitative profiling of the binding specificity, versatility and biological activity of millions of antibodies, reflects the total immune response.
MVA technology enables to obtain quantitative and qualitative antibody binding profiles (immunoprofiles). A binding profile can be made to describe a single molecule up to individuals or populations. An immunoprofile describes the state of the immune system and its ability to protect the body. That is considered an innovative tool interpreting health related data for diseases and health conditions and propels the caregivers towards a new level of understanding regarding prevention and treatment. Also, MVA allows offering reliable services such as epitope mapping, antibody analyses, immunogenicity assessment, etc. to research groups and the biotechnology industry.
MVA technology is based on screening of combinatorial peptide display library, next generation DNA sequencing and proprietary bioinformatics analysis.
Epitope mapping defines the binding specificity of an antibody. Protobios’s Mimotope Variation Analysis (MVA) technology gives a detailed description of epitopes and mimotopes and has several advantages over other technologies.
In a standard MVA Epitope mapping protocol, three million antibody-captured peptides from the peptide display library will be analyzed and clustered. In general, monoclonal antibody analysis will result in one epitope, whereas polyclonal antibody analysis may result in numerous epitopes.
The immunogen competition assay (ICA) is a recommended procedure for confirming the epitope-specific binding activity of antibodies. The ICA provides means to discriminate between true and non-specific (crossreactive)
targets for the antibody.
Advantages of MVA Based Epitope Mapping:
• Precise – Identifies and distinguishes all, including overlapping, epitopes.
• Quantitative and qualitative – Epitope description includes Positional Weight Matrix of amino acid residues in the peptide epitope motif.
• Universal – No need for prior knowledge of the immunogen.
• Cost effective – Saves money compared to competing techniques, such as peptide array.
