I am having quite a bit of difficulty using this probe. It seems that there is no standardized way to analyze the data in Flowjo. I have also read many papers that say you need to compensate if you use the 488 nm laser, but how do you compensate with just one dye? Additionally, how do you determine the ratio of red/green fluorescence? Is it simply the MFI red/MFI green or does the calculation require normalization to the positive control?
