[Histonet] hematoxylin

[Jose Luis Palazon Fernandez]

Dear List-members

greetings. I would like to know if there is a substitute for the "celestine blue/hematoxylin" staining of nucleus that can resist a posterior acidic counterstain. I need to apply a protocol that uses this nuclear staining method but I dont have celestine blue and the company that suplies it says that it would last 2 months to supply the stain

Thanks in advance 

José Luis
