Green fluorescent protein and other fluorescent proteins provide powerful tools for high content analysis of cellular processes. Engineering fluorescent protein sensors for expression in cellular assays requires consideration of a wide range of design factors to produce fusion proteins capable of generating informative and biologically relevant data while meeting the rigorous demands of high content screening. The target protein, fluorescent protein, host cell line, construct components and orientation, expression level, and other factors all contribute to the performance of the sensor. This chapter reviews the process of selecting an optimum combination of these design elements for engineering cells for high content analysis.
