Microarray
Microarray — A high-density array of peptide spots on a solid surface used for parallel screening of binding interactions and immune responses.
What Is a Peptide Microarray?
A peptide microarray is a glass slide or membrane spotted with thousands of different peptides at defined positions, enabling high-throughput screening of peptide-protein interactions, epitope mapping, kinase substrate profiling, and autoantibody detection in a single experiment.
Applications
- Epitope mapping: Overlapping 15-mers spanning a protein sequence probed with patient sera
- Kinase profiling: Peptide substrate arrays identify kinase specificity and activity
- Antibody specificity: Verify antibody binding specificity against thousands of peptide sequences
- Density: 1,000-100,000 peptides per standard glass slide
