What role does immunohistochemistry play in evaluating treatment effects?
Immunohistochemistry (IHC) is a powerful technique used to evaluate treatment effects. IHC involves the use of antibodies to detect specific antigens in cells and tissues. For example, in assessing hormonal therapy in breast cancer, IHC can detect the presence or absence of estrogen and progesterone receptors, which helps in determining the treatment response. Similarly, IHC can be used to detect markers of apoptosis or proliferation.
