Propidium-Iodide is also an intercalating agent but with no binding preference for distinct bases. In the nucleic acid bound state, its excitation maximum is at 538 nm.

Nettet1. sep. 1994 · This method is based on the detection of differences in chromatin condensation with Hoechst 33342 as a probe and the detection of dead cells with propidium iodide as a probe for membrane damage. By this method it was possible to detect, in the same sample and at the same time, intact cells, cells undergoing … NettetHoechst and DAPI are popular blue fluorescent, nuclear-specific dyes that can be used to stain live or fixed cells. Both DAPI and Hoechst are minor-groove binding dyes with a preference for A/T-rich regions of DNA over G/C-rich DNA. The dyes have minimal fluorescence in solution, but become brightly fluorescent upon binding to DNA.
