The specific non-invasive control of intracellular signaling events requires advanced tools that enter cells by diffusion and are controllable by light. Here, we detail the synthesis and application of membrane-permeant caged inositol pyrophosphates with respect to cell entry and cell distribution. We recently published the synthesis of these tools as well as their effect on PH-domain localization in HeLa cells and oscillations of the intracellular calcium concentration in β-cells, which are known to drive insulin secretion. In this chapter, we discuss the possibilities and limitations when using cell-penetrating inositol pyrophosphates. We provide a detailed protocol for the application in live mouse β-cells and we discuss the image analysis needed for following effects on calcium signaling.
