摘要: Glial fibrillary acidic protein (GFAP) was present in cell cultures derived from human fetal brain tissue as determined by indirect immunofluorescence (IF) and immunoperoxidase (IP) staining using rabbit anti-human GFAP antisera. The IF IP techniques were comparable localizing the cytoplasmic distribution frequent perinuclear concentration of cells. horseradish peroxidase technique more sensitive a 1:20–1:40 dilution anti-GFAP serum could be applied initial step compared to 1:10 for staining. Sequential studies subcultivated lines these indicated that some become GFAP-negative rapidly, whereas other remain GFAP-posifive no less than ten subcultivations vitro. GFA never any PMLSV40-transformed
