Protein Arrays: Methods and Protocols is an introduction to protein array technology and its application to the multiplexed detection of proteins. Although protein array technology has some roots in gene array technology, it can only be described as a distant relative. Unlike DNA, with its established rules of base pairing, and therefore predictable biochemical behavior, proteins are rich with diversity. Proteins can be large or small, compact or extended, basic or acidic, hydrophobic or hydrophilic, and so on. Just as importantly, their behavior is determined by the environment in which they...
