Immunohistochemistry (IHC) is a widely applied experimental method used to examine tissue antigen expression and behavior with the use of an antibody conjugated to a secondary tag for visualization. IHC consists of a tissue preparation phase, an antibody-staining phase, and a result analysis phase - all of which may lead to skewed results if not properly performed. One way to ensure that IHC staining results are in fact demonstrating protein behavior and not a side effect the experimental process is to use IHC controls within each expe
