[Histonet] Histochoice fixation

[ayanava chakravarti]

I wish to test how the Histochoice ( Amresco)  fixative works in lieu of 4% paraformaldehyde for my frozen brain sections in order to avoid the subsequent antigen retrieval step. 
Can anybody share their experience how it works ? For how much time should I use it for fixation?

Thanks
