[Preparation of polyacrylamide gel electrophoresis for human chorionic gonadotropin chimeric peptide 12 expressed in E. coli].

In recent years, development of chimeric peptide (CP) immunogens is a trend in the vaccinological field. The CPs contain a B cell epitope(s) of target antigen and a promiscuous self - or foreign- T cell epitope(s). However, such constructed CPs were all expressed in prokaryotic or eukaryotic systems at lower levels.
