Poorly differentiated nasopharyngeal carcinoma (SUNE 1) cell line was cultured with Epstein Barr virus (EBV) BHRF1, DNase, thymidine kinase (TK) and nuclear antigen 1 (EBNA1) antisense oligodeoxynucleotide (ASO) for 48 h respectively.

• 用不同浓度的EB病毒 4种 (BHRF1、DNA酶、核抗原 1及胸苷激酶 )反义寡核苷酸片段 ,(antisenseoligodeoxynucleotide ,ASO)分别与含 10%25胎牛血清或不含胎牛血清的人低分化鼻咽癌细胞株 (SUNE 1)共同培养 4 8h。
