摘要: The unlabeled peroxidase-anti-peroxidase method was used to stain glial fibrillary acidic (GFA) protein in the optic nerve of developing albino rat. Optic nerves from animals ranging age day birth adulthood were embedded paraffin following fixation with various agents for times 30 minutes 48 hours. GFA activity demonstrable at large astrocytic processes alcohols or Perfix short intervals, but not 4% 2% buffered paraformaldehyde solutions. With increasing age, could be demonstrated using higher aldehyde concentrations, longer times, and embedding schedules. At all ages greater treatment nonaldehyde fixatives rather than those containing formaldehyde glutaraldehyde. majority protein-containing confined planes which perpendicular axons nerve. tangential longitudinal became more numerous until, mature nerve, best characterized as being multidirectional.
