The Eptstein-Barr virus (EBV)-determined nuclear antigen (EBNA) was solubilized from isolate nuclei of two EBV-transformed cell lines- Raji and AW-Ramos, by high-salt treatment. Its DNA-binding properties were studied by DNA-cellulose chromatography and a 51Cr release complement fixation assay. EBNA binds to both double-stranded and single-stranded calf thymus DNA, showing a higher affinity to double-stranded DNA. There was no detectable difference in the DNA binding of EBNA prepared from Raji and AW-Ramos cells.
通过高盐处理,从两种爱泼斯坦 - 巴尔病毒(EBV)转化的细胞系——拉吉(Raji)细胞系和AW - 拉莫斯(AW - Ramos)细胞系的分离细胞核中溶解出EBV决定的核抗原(EBNA)。通过DNA - 纤维素色谱法和51Cr释放补体固定试验研究了其DNA结合特性。EBNA能与双链和单链小牛胸腺DNA结合,对双链DNA显示出更高的亲和力。从Raji细胞系和AW - Ramos细胞系制备的EBNA在DNA结合方面没有可检测到的差异。
