[Histonet] trichrome/ frozen cardiac tissue

[Molinari, Betsy]

Hi,
 I have some frozen house hearts that were perfused with 4% paraformaldehyde. I found protocols for FF, but not fixed frozen. I tried staining them with my usual Gomori I use on my paraffin blocks but the doc thinks they picked up too much red, not enough green.
Any suggerstions..I need to get them done today, they were brought up to RT this morning.
Thanks.
