The antibody array has become a powerful technology in recent years and is widely used to detect the expression levels of various proteins such as cytokines, growth factors, chemokines, and angiogenic factors, some of which are involved in cancer progression. In this chapter, we describe a protein array technology called enhanced protein profiling array, which can simultaneously and quantitatively measure the expression levels of a few proteins in hundreds or thousands of samples, and an example of its use is presented.
Keywords: Antibody array; Cytokine antibody array; Enhanced protein array; Quantitative array; Throughput array.
