In histology, CACT can be studied using various techniques such as immunohistochemistry and immunofluorescence. These methods involve the use of specific antibodies that bind to CACT, allowing for its visualization under a microscope. These techniques help in localizing CACT within cells and tissues, providing insights into its distribution and abundance. Additionally, electron microscopy can be used to study the ultrastructure of mitochondria and the precise localization of CACT within the inner mitochondrial membrane.
