Abstract: | Abstract: Total poly(A)+ RNA was isolated from fetal calf spinal cord, adult rat spinal cord, and young rat brain, and was translated using the rabbit reticulocyte lysate system. The amount of glial fibrillary acidic protein in the translation products was measured by immunoprecipitation with antiserum against glial fibrillary acidic protein. RNA from fetal calf spinal cord could direct glial fibrillary acidic protein synthesis such that this protein comprised approximately 1.4% of the total products. RNAs from adult rat spinal cord and brain could direct glial fibrillary acidic protein synthesis much less efficiently, with this protein comprising <0.3% of the total products. These results suggest that the gene for glial fibrillary acidic protein is strongly expressed in fetal calf spinal cord and that this tissue is an enriched source of mRNA encoding glial fibrillary acidic protein. |
