The GFP Toolbox includes four GFP-based tools: Folding Reporter, SuperFolder,
Insertion, and Split GFP. This suite enables researchers to perform experiments
impossible to do with conventional GFPs. The toolbox is simple to use, versatile,
and each component has only one moving part. The toolbox includes genetically
encoded tags as short as 15 amino acids, with little or no effect on passenger
protein localization, behavior, folding, or solubility.
