Monoclonal antibodies were isolated from mice immunized with chicken gizzard desmin. Antibodies reacting with desmin on immunoblots and selectively decorating chicken and rat intestinal smooth muscle as well as the Z-line in striated muscle, were selected for this study. Based on their staining pattern on cryostat sections of chicken and rat cerebellum, spleen, kidney, aorta and femoral artery, monoclonal supernatants could be divided in three groups: (i) antibodies decorating astrocytes and vascular smooth muscle; (ii) antibodies decorating only vascular smooth muscle; (iii) antibodies decorating only astrocytes. Antibodies in group (i) and (iii) also stained GFA-negative Bergmann glia in chicken cerebellum. It is proposed that desmin may vary depending on the histological localization.
