How is Caspase 9 Detected in Histological Samples?
Detection of Caspase 9 in histological samples is typically performed using immunohistochemistry (IHC) or immunofluorescence techniques. These methods involve the use of specific antibodies that bind to Caspase 9, allowing for its visualization under a microscope. The presence of active Caspase 9 can be identified by its characteristic staining pattern, which is often localized to the cytoplasm of apoptotic cells.
