Dongxue Hu Hi Dongxue. Did you measure the ratio of MFI of green fluorescence to the red one? But it seems that will be the same result. Have you fixed this problem?

Dongxue Hu

Actually, I did not analyze the figure correctly. The green fluorescent signal increased indeed. If I set the X-axis properly, it will be able to see the change.

@Dongxue Dongxue, good for you.
