WebProbably around 90% of compensation issues actually arise due to the use of insufficiently bright controls. If your sample stains brighter than your control, the software cannot accurately calculate the amount of secondary fluorescence and will overcompensate or under compensate the data.

WebIncorrect flow rate. Ensure that your samples are being run at the lowest flow rate setting on your cytometer. High flow rates will give rise to high coefficients of variation (CVs), leading to a loss of resolution of the different phases of the cell cycle. Insufficient staining with Propidium Iodide/RNase (PI) solution. Webneously in flow cytometry detection problems may arise. In general, the emission spectra of the fluorescent dyes are inher-ently wide because the emitted photons result from transitions of the electrons from the first excited state to different vibra-tional levels of the ground state. In addition, for sensitivity
