Fig. (2) Immunofluorescence localization of α- and β-DG in human skeletal muscle sections. C: control, P1-P7: patients. The β-DG subunit was detected with two monoclonal antibodies, 43DAG/8D5 and BD, that recognized the β-DG cytoplasmic tail and its extracellular domain, respectively. α-DG was detected with the monoclonal antibody IIH6 (lot 22991), raised against an undefined carbohydrate epitope (red arrow), and with a polyclonal antibody directed against its C-terminal region.
