In histology, the study of aromatase involves various techniques to identify and quantify its presence in tissues. Immunohistochemistry (IHC) is a common method used to detect aromatase by utilizing specific antibodies that bind to the enzyme. This technique allows researchers to visualize the distribution and intensity of aromatase expression within tissue sections. Additionally, in situ hybridization (ISH) can be used to detect aromatase mRNA, providing insights into the gene expression patterns of this enzyme.
