[Histonet] PH of Toluidine blue and aldehyde fuscin staining

[FU,DONGTAO]

Hi, all

  we will do some special staining of T blue and aldehyde fuscin. 
We will make some solutions by ourself. I notice some buffers need 
to measure PH value. But they are dyes, so you can not use dip 
paper. How do you measure them?

  Thank you,

Ann
