Hoechst cell cycle

NettetHoechst 33258 nucleic acid stain is a popular nuclear counterstain that emits blue fluorescence when bound to dsDNA. Its uses are similar to Hoechst 33342 (H-1399) for counterstaining, apoptosis and cell cycle … NettetThe cell cycle is a cycle, rather than a linear pathway, because at the end of each go-round, the two daughter cells can start the exact same process over again from the …
