Antigen Retrieval Terms for IHC

Antigen retrieval (AR) is a fundamental part of any IHC protocol. However, with so many different names for this one process, it can be difficult to recognize what an individual protocol or paper is referring to.

To get to the bottom of these questions, we must take a look at the purpose of antigen retrieval and which techniques for antigen retrieval are in use today.
