Peptide Mapping Arrays

Peptide mapping arrays for precise antibody epitope identification and characterisation

Peptide mapping arrays screen hundreds of overlapping peptides at the same time in a single hybridisation, building a positional binding profile across a target protein. Synthesised peptides tiling across the target protein sequence are printed onto glass slides, and after you incubate your antibody sample on the array, a fluorescent secondary antibody detects where the antibody has bound to give a positional binding map. PD-L1 epitope mapping arrays are available for three antibody species: human IgG, mouse IgG, and rabbit IgG, each covering the PD-L1 sequence with overlapping peptides. This lets you pinpoint the antibody binding region precisely, useful for antibody validation, biosimilar characterisation, and epitope binning studies.

Pick by array content.

1. Application. Full-tiling overlapping peptides for de novo epitope mapping. Curated motif libraries for substrate profiling. Custom peptide arrays for specific protein families.
2. Peptide length. 5- to 20-mer typical; shorter peptides may miss conformational epitopes.
3. Scanner. Standard 532/635 nm microarray scanners.
4. Custom design. For non-catalogue targets factor design and synthesis time into your project.
5. Conformational epitopes. Peptide arrays alone insufficient; pair with native-protein binding assays.
