Poly-GA immunohistochemistry (A) on formalin fixed paraffin embedded cerebellum sections shows a similar distribution to p62 antibody (B) and reliably identifies neuronal cytoplasmic inclusions and neurites in cases with known C9orf72 repeat expansion. This is useful in the research setting where genetic testing has not been performed in life or suitable tissue is not avilable post-mortem.
多聚-GA 免疫组化(A)在福尔马林固定石蜡包埋的小脑切片上显示出与 p62 抗体(B)相似的分布,并可靠地识别出具有已知 C9orf72 重复扩展的病例中的神经元细胞质包含物和神经突。这在研究环境中很有用,在这种环境中,生前未进行基因检测,或死后没有可用的合适组织。
