Elizabeth, You can try to lower the pH of the eosin a bit. Add some acetic acid. Use absolute alcohol after the eosin for differentiating/dehydrating. Jennifer

Our standard protocol works well for our own tissue, but the fish look much more washed out. I am using alcoholic eosin Y, have tried both water and alcohol before and I have varied the alcohol differentiation steps after the Eosin. I also extended the time in Eosin and increased the wash after bluing to make sure the sections are not basic. Any suggestions would be appreciated. Thank you. Elizabeth M.
