    • The chimeric antibody to pre-S2 of HBV (I) of subtype adr is prepared by; A (for heavy chain) (1) cutting DNA of aLys-30 of 8.9 kb with BanHI and BglII for HuCr1, (2) inserting that fragment into plasmid PSV2-neo to get PVS2neo-hCr1, (3) cutting DNA of pMHG-S2 of 9.4 kb and adding EcoRI linker, and (4) inserting that fragment into PVS2neo-hCr1 to get plasmid pHS2-neo (KCTC 0031BP); (for light chain) (5) extracting hygro gene from pSVhygro, (6) cutting pHuCk with EcoRI to get HuCk gene, (7) cutting pMGK-S2 with XmnI to get MuVk and Ek genes and adding XhoI linker, (8) inserting genes of (5), (6), (7) into plasmid pBluescript SK+ to get plasmid pLS2-hygro, C (KCTC 0032BP), (for transfectoma) (9) transfecting DNA fragments of PvuI treated pHS2-neo and SpeI/NotI treated pLS2-hygro to get A-44 (KCTC 0033BP). From A-44 transfectoma, 55kd size of heavy chain and 25kd of light chain of (1) were purified.
    • 亚型adr的HBV(I)前S2的嵌合抗体通过以下方法制备: A(用于重链)(1)用BamHI和BglII切割用于HuCr1的8.9kb的Lys-30 DNA,(2)将该片段插入质粒PSV2-neo以获得PVS2neo-hCr1,(3)切割pMHG- S2,9.4kb,加入EcoRI接头,(4)将该片段插入到PVS2neo-hCr1中,得到质粒pHS2-neo(KCTC 0031BP); (轻链)(5)从pSVhygro提取hygro基因,(6)用EcoRI切割pHuCk得到HuCk基因,(7)用XmnI切割pMGK-S2以获得MuVk和Ek基因并加入XhoI接头,(8)插入 (5),(6),(7)的基因转化到质粒pBluescript SK +中以获得质粒pLS2-hygro,C(KCTC 0032BP)(用于转染瘤)(9)转染PvuI处理的pHS2-neo和SpeI / NotI的DNA片段 治疗的pLS2-hygro得到A-44(KCTC 0033BP)。 从A-44转染瘤,纯化了55kd大小的重链和25kd的轻链(1)。
