Cell Cycle Analysis by Flow Cytometry - Thermo Fisher …

Nettet1. jul. 2015 · In this unit, two protocols are described for analyzing cell cycle status using flow cytometry. The first is based on the simultaneous analysis of proliferation-specific marker (Ki-67) and cellular DNA content, which discriminate resting/quiescent cell populations (G0 cell) and quantify cell cycle d … NettetCell cycle analysis by quantitation of DNA content was one of the earliest applications of flow cytometry. The DNA of mammalian, yeast, plant or bacterial cells can be stained by a variety of DNA binding dyes. The premise of these dyes is that they are stoichiometric, i.e. they bind in proportion to the amount of DNA present in the cell. jason taylor invicta watch
