Histological analysis of immune organs typically involves the use of various staining techniques. Hematoxylin and eosin (H&E) staining is commonly used to visualize the general architecture of tissues. Immunohistochemistry (IHC) can be employed to detect specific cell markers, allowing for the identification of different immune cell types. Advanced imaging techniques, such as confocal microscopy, may also be used to study the spatial organization and interactions of immune cells within these organs.
