Analysis of structure of virus-like particles of hepatitis B surface antigen expressed in recombinant Saccharomyces cerevisiae by high performance liquid chromatography
Objective To analyze the structure of virus-like particles(VLPs)of hepatitis B surface antigen(HBsAg)expressed in recombinant Saccharomyces cerevisiae by high performance liquid chromatography(HPLC). Methods The peak profiles of three batches of purified VLPs of HBsAg expressed in S. cerevisiae were analyzed by HPLC using SDSfree PBS and SDS-containing PBS as mobile phases separately. Results Each of the three batches of purified HBsAg showed a single VLP peak with relative molecular mass of 2 000 000 at(15...

乙型肝炎表面抗原(hepatitis B surface antigen,HBsAg)是制备乙型肝炎疫苗的关键有效成分。重组酵母细胞表达的HBsAg的P24亚基是由226个氨基酸组成的多肽,含14个游离或非游离的半胱氨酸,相对分子质量约为24 000[1]。重组酿酒酵母(Sacchar-omyces cervesiae)细胞表达的相对分子
