Dear Yonghua,

We use
0.5% phenol red in DPBS (Sigma, cat. no. P-0290)
This solution comes already made.  I use it at 5X (1ul per 5ul total

Dear all,

I am trying to make a 5X stock phenol red solution for microinjection.
When I searched the literature, I found different formulas from
different papers, e.g., (0.1% phenol red, 100mM KCl) or (0.5% phenol
red, 240 mM KCl) or (1% phenol red, 200mM KCl). Do you have any idea
that which one gives the best result in your hands?

Another question is that when I prepared 1.2% phenol red solution, it
was really hard for the phenol red to be dissolved completely. Does
anybody have any suggestion for that?

Thanks a lot!
