about phenol red solution for microinjection
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

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!

Re: about phenol red solution for microinjection
several studies of microinjection techniques on aquatic species have been used phenol red to mix the DNA solution as a tracer is encouraged to allow confirmation of injections ; for making the injection-solution visible 0.1 % phenol-red was added; injection solutions contained 2 % phenol red to aid in estimating the volume of solution injected into each embryo.
Phenol red will be not toxic to fish embryo (abnormality) if we use it at < 0.01 %. I am doing research with 0.02% phenol red.
