RE: [Histonet] Sucrose and paraffin

From:"Molinari, Betsy"

 I have heard of sucrose for cryoprotection, but these are tissues that
have been fixed in 10% NBF and they want to then put in sucrose then
process for paraffin. I just don't understand the rational or if there
would be any advantage for IHC.

I used sucrose in research for cryo protection. We used 10, 20. and 30%
sucrose to protect the tissue from freeze artifact as we were doing
frozen sections on it. I don't think that sucrose will do anything for
antigen staining....

Hi all,

 I have no experience with IHC but (once again) had a researcher ask me
if placing tissue in sucrose after 10% NBF is helpful in antigen
