WebDuring apoptosis the DNA becomes condensed, but this process does not occur during necrosis. Nuclear condensation can therefore be used to distinguish apoptotic cells from healthy cells or necrotic cells. Dyes that bind to DNA, such as Hoechst 33342 or 4′,6-diamidino-2-phenylindole (DAPI), can be used to observe nuclear condensation. WebDescription. Hoechst 33342 is a popular cell-permeant nuclear counterstain that emits blue fluorescence when bound to dsDNA. This dye is often used to distinguish condensed pycnotic nuclei in apoptotic cells and for cell cycle studies in combination with BrdU. It is also available in solution (H-3570).
