[Histonet] Staining coral tissues embedded in resin

From:Laura Hunt



Hi everyone,


I am new to the forum.  I am working on coral tissues embedded in  
Immunobed resin and paraffin.  We would like to stain both with H&E  
and Azure II /Basic Fuchsin.  I have never tried staining plastic with  
H&E.  Any suggestions or comments would be great!  Since corals have a  
calcium carbonate skeleton, the tissues were decalcified in a EDTA  
solution.

>> Hello,
>> Recently we bought a sakura slide writer that uses ink to print. The

>> label.  If

>> buying a Sakura slide write as it has a very unfriendly Access based
>> program and the writer does not work with charged slides.  This has
