Final answer:
Immunohistochemistry is utilized to attach antibodies to cells that express specific proteins or antigens, such as those found in tumor cells, viral particles, or bacterial cells. Normal tissue cells are not typically the focus of this technique.
Step-by-step explanation:
Immunohistochemistry would be best used to attach antibodies to all of the following EXCEPT normal tissue cells. Immunohistochemistry (IHC) is a technique used to detect the presence and location of proteins in tissue sections by exploiting the principle of antibodies binding specifically to antigens in biological tissues.
IHC is a powerful method for detecting specific proteins within tissues, making it useful for identifying tumor cells, viral particles, and bacterial cells. These entities typically express specific markers that can be targeted by antibodies. For example, a monoclonal antibody (mAb) against CD8 can be used to stain CD8 cells in tissue sections, which is beneficial for studying diseases such as AIDS.
