Assessment of Patient BI and control astrocyte GFAP immune-staining in occipital cortex and occipital subcortical white matter using peroxidase staining technique and anti-GFAP antibodies as described in Methods. a Peroxidase staining with GFAP in samples from BI occipital cortex showing a reactive astrocyte with numerous “beaded” processes (400X). b Peroxidase staining with GFAP in BI samples from occipital subcortical white matter showing increased GFAP immune-staining and a reactive phenotype. Representative photographs are shown
