采用辣根过氧化物酶标记的花生凝集素(PNA),对68例人鼻咽粘膜上皮和鼻咽癌的石蜡切片进行染色。结果表明,鼻咽癌细胞中PNA受体的分布及含量与鼻咽粘膜上皮相比显著不同,提示鼻咽癌细胞具有不完整的糖蛋白合成。
Horseradish peroxidase-labeled peanut agglutinin (PNA) was used to stain 68 paraffin sections of human nasopharyngeal epithelium and nasopharyngeal carcinoma. The results showed that the distribution and content of PNA receptors in nasopharyngeal carcinoma cells were significantly different from that of nasopharyngeal epithelium, suggesting that nasopharyngeal carcinoma cells have incomplete glycoprotein synthesis.
