Propidium iodide (PI) is a popular red-fluorescent nuclear and chromosome counterstain. Since propidium iodide is not permeant to live cells, it is also commonly used to detect dead cells in a population. PI binds to DNA by intercalating between the bases with little or no sequence preference.
Chemical synthesis reagents are essential to transform building blocks into target molecules quickly, safely, and cleanly. The Thermo Scientific portfolio includes over 5,000 organic synthesis reagents spanning a wide range of R&D applications.
