用sternbergef氏过氧化物酶一抗过氧化物酶法对福尔马林固定、石腊包埋的组织切片进行神经胶质原纤维酸性(GFA)蛋白(联合星形细胞蛋白)的免疫细胞化学定位正普遍用于帮助诊断人体脑肿瘤。对GFA蛋白抗体显阳性反应的有如下一些肿瘤:星形细胞瘤,成星形细胞瘤,成神经胶质细胞瘤,室管膜细胞瘤,室管膜下细胞瘤和混合性胶质瘤内的星形细胞。对GFA蛋白抗体显阴性反应的有原始神经上皮细胞,神经节细胞,少突胶质细胞, Immunocytochemistry of glial fibrillary acidic (GFA) protein (in combination with astrocyte protein) was performed on formalin-fixed, paraffin-embedded tissue sections using sternbergef’s peroxidase primary antibody peroxidase method Positioning is commonly used to help diagnose human brain tumors. Some of the tumors that were positive for GFA protein antibodies were astrocytoma, astrocytoma, glioblastoma, ependymoid cell tumor, subduedular cell tumor and mixed glioma Astrocytes. Negative responses to GFA antibodies include primary neuroepithelial cells, ganglion cells, oligodendrocytes,
