MtoZ Biolabs has launched the high-throughput peptide epitope mapping service which enables systematic screening and precise localization of potential epitope regions within peptide sequences. This service is widely applied in antibody development, vaccine design, and protein interaction studies, providing efficient and reliable data support for epitope identification and functional analysis.
Overview
Epitope mapping is a technique used to determine the key amino acid regions within an antigen that are recognized by antibodies or receptors, and it serves as an important tool in antibody screening, vaccine development, and protein interaction research. Peptide-based epitope mapping identifies linear epitopes and function-related regions by synthesizing peptide segments that cover the target sequence and assessing their binding capacity to antibodies. Compared with traditional mutagenesis or structural biology methods, this strategy offers high throughput, strong flexibility, and rapid analysis, making it highly effective for supporting antigen characterization and molecular design.

High-Throughput Peptide Epitope Mapping Service at MtoZ Biolabs
1. Linear Peptide Epitope Mapping
MtoZ Biolabs uses synthetic peptide libraries or truncation strategies to systematically scan the target antigen sequence, thereby accurately identifying linear epitope regions presented by continuous amino acid residues and supporting rapid localization of key binding fragments.
2. Conformational Peptide Epitope Mapping
By integrating structural biology approaches such as X-ray crystallography or nuclear magnetic resonance (NMR), MtoZ Biolabs can resolve conformational epitopes that depend on three-dimensional structural features, helping to reveal the stereospecific recognition patterns of antibodies toward folded peptides or proteins.
