I'm looking for input on the latest theories of duration of fixation for routine IHC. In the past, it was thought that tissues should be removed from 10% NBF after a max of 72 hours, and if not immediately processed, transferred to 70% ethanol until processed to retain antigenicity. What is the current thinking/trends? Over the last couple of years, I have heard that leaving tissues in 70% ethanol may be doing more harm than good, and it's NOT a good idea to leave them in alcohol for extended periods of time. I would appreciate your input, or point me towards any new data.
