Antibody arrays are advanced multiplexed immunoassay platforms that allow parallel detection and quantification of multiple proteins from minimal sample volumes. These arrays utilize immobilized antibodies specific to target proteins or their post-translational modifications, enabling high-throughput protein profiling essential in biomedical research and clinical diagnostics.
Applications in Research and Clinical Diagnostics
Antibody arrays are deployed across studies in basic biology, systems biology, and clinical diagnostics. They facilitate:
- Profiling protein expression patterns and signaling networks.
- Investigating post-translational modifications such as phosphorylation and glycosylation.
- Identifying biomarkers for diseases through proteome signature analysis comparing healthy and disease states.
- Drug mechanism studies by tracking targeted protein changes.
Such capabilities provide valuable data for biomarker discovery, disease diagnosis, and therapeutic monitoring, often complementing mass spectrometry-based proteomics.
The continued evolution of antibody array technology is expected to enhance personalized medicine by enabling precise and comprehensive protein biomarker analyses from minimal biological samples.
