Antibody microarrays for high-throughput, multianalyte analysis.

Enzyme-linked immunosorbent assay (ELISA) microarray technology promises to be a powerful tool for detecting and validating protein biomarkers, especially panels of biomarkers. ELISA microarrays are capable of high-throughput analysis of multiple proteins using small sample volumes. In this chapter we review the literature on the use of antibody microarrays for biomarker discovery and validation. We also described the methodologies we employ to obtain high-quality data through protocol optimization and data calibration.
