[Histonet] Alcian Yellow

[Frouwke Kuijpers]

Can somebody tell me how to make an Alcian Yellow solution PH 2,5? And do you have to filter it before use? I already know that 0,2% is the max. but still I get it not dissolved.

And on the histonet archive I read that Alcian Yellow is not made anymore. We still have a lot of it, does it has an expiring date?

Thanks Frouwke
