Dear Patsy,
Some years back I was planning to make up multitumor (sausage) tissue
blocks for immunohistochemistry controls, but never got around to it.
My recollection is that after optimal fixation in formalin you would
hold the tissue in 70% alcohol until ready to process. You might find
some information in an article published by Battifora H. "The multitumor
(sausage) tissue block: Novel method for immunohistochemical antibody
testing. Lab Invest 1986; 55:244-248. Katri:-)
