An antibody array, also known as a protein array or immunoassay array, is a high-throughput technology used to simultaneously detect and measure the levels of multiple proteins or antibodies in a biological sample. It involves immobilizing a variety of antibodies or proteins in an ordered array format on a solid surface, such as a glass slide or a microchip.

When a sample containing proteins or antibodies of interest is applied to the array, specific interactions occur between the immobilized antibodies and the target molecules in the sample. These interactions can be detected and quantified using various techniques, such as fluorescence, chemiluminescence, or colorimetry.

Antibody arrays enable researchers to profile and analyze protein expression patterns, identify biomarkers, study protein-protein interactions, and explore disease-related protein changes in a high-throughput manner. They
