(a) Immunoperoxidase labeling of the t(2; 5)+ cell line with antibody ALK1. The nuclei, cytoplasm, and nucleoli are strongly labeled by antibody ALK1. During mitosis, the staining of these cells becomes cytoplasmic. (b) Immunoperoxidase labeling of a cryostat section of basal ganglia showing weak labeling of a glial cell (arrow).
