Remember that you can validate your testing for longer fixation. Run parallel ER/PR/Her2 testing with tissue fixed for various lengths of times and look at the staining correlation between groups. Most likely your longer fixation won't be a problem. If you do see a drop off with longer times you can probably adjust antigen retrieval time to alleviate that.

We are running into this problem since we don't currently work Saturday hours. Thank you!
