In histological studies, ankyrin 2 can be detected using immunohistochemistry (IHC), immunofluorescence (IF), and Western blotting techniques. Specific antibodies against ankyrin 2 are used to stain tissue sections, allowing visualization of its distribution and localization within cells. These techniques are essential for understanding the role of ankyrin 2 in various tissues and its involvement in different physiological and pathological conditions.
