Dear members,
I have a problem with my fluorescence pH probe.
This probe has two different fluorescence emissions in PBS (pH 6 green emission, pH 9 red emission)
When I did the cellular image with HeLa cell (pH 6 and pH 9 with PBS or BTB solution), the probe did not show red emission at pH 9.
It gives only small difference in its fluorescence emission.
How can I control the cellular condition to solve this problem.
I'm waiting for your kind answer.
Thank you.
