(1) Using a model system for gliosis (laceration-type injury of rat spinal cord), we were able to show that astrocytes responding to central nervous system injury exhibit greatly enhanced staining for J1-31 antigen (Predy et al.

(3) Rules and regulations facilitate distributing divisible benefits to producer interests in a politically predi-table way.
(4) Yet J1-31 antigen is distinct from GFAP (Predy et al.
(5) By immunofluorescence microscopy, MAb J1-31 stains those cells that are also stained by antiserum to glial fibrillary acidic protein (GFAP), namely astrocytes, retinal Müller cells, and tanycytes in the ependyma (Predy et al.
