以往的实验表明 ,乙型肝炎病毒 (ｈｅｐａｔｉｔｉｓＢｖｉｒｕｓ,ＨＢＶ)的ｐｒｅＳ1-(2 1-4 7)序列直接参与病毒与细胞膜受体的粘附 ;ＨｅｐＧ2细胞膜上存在ＨＢＶ受体活性的蛋白质。本文作者利用人工合成的 4 ｐｒｅＳ1 (2 1 47)序列 ,通过亲合色谱法从去垢剂溶解的ＨｅｐＧ
Previous experiments showed that the preS1- (2 1-4 7) sequence of hepatitis B virus (HBV) is directly involved in the adhesion of the virus to the cell membrane receptor; and the HBV receptor activity protein exists in the HepG2 cell membrane. Using the synthetic 4 preS1 (2147) sequence, the authors used affinity chromatography to remove HepG from detergent
