We used six monoclonal antibodies (MAb) recognizing epitopes within keratan sulfate (KS) chains for an immunocytochemical study of adult rat brain. One of the MAb selectively stained microglia and their ramified processes. KS-positive cells were found throughout the CNS in both paraffin-embedded and cryostat sections; the greatest number were present in hippocampus and brainstem. In the cortex the positive processes of some cells surrounded neuronal somata. In the white matter the processes were both parallel and perpendicular to the axon bundles. Double staining showed that KS-positive cells did not express astrocytic or oligodendroglial markers. By immunoelectron microscopy, the positivity was localized around the perikarya and cell processes of small cells with peripheral chromatin clumps and dark cytoplasm, which often contained secondary lysosomes. The KS-positive cells did not contribute to myelin sheaths and were not surrounded by a basal membrane. In addition to the cellular staining, three other MAb stained the white matter diffusely. Anti-KS MAb are therefore proposed as immunohistochemical markers for ramified microglia in both paraffin and cryostat sections of adult rat brain.

An autoradiographic method for the measurement of the rate of valine incorporation into brain proteins is described. The transfer coefficients for valine into and out of the brain and the rate of valine incorporation into normal rat brain proteins are given. The valine incorporation and the transfer constants of valine between different biological compartments are provided for 14 gray matter and 2 white matter structures of an adult rat brain. The rate of valine incorporation varies between 0.52 ± 0.19 nmol/g/min in white matter and 1.94 ± 0.47 in inferior colliculus (gray matter). Generally, the rate of valine incorporation is about three to four times higher in the gray matter than in the white matter structures.
