Beschreibung
Zusammenfassung:The present invention relates to a chimeric papillomavirus L1 protein and a polynucleotide encoding same, as well as HPV virus-like particles and a preparation method therefor. The chimeric papillomavirus L1 protein comprises an N-terminal fragment derived from the first-type papillomavirus L1 protein, wherein the N-terminal fragment maintains the immunogenicity of the L1 protein corresponding to HPV types; and a C-terminal fragment derived from the second-type papillomavirus L1 protein and having better characteristics of expression quantity and solubility than those of other types of L1 protein, wherein the chimeric papillomavirus L1 protein has the immunogenicity of the L1 protein corresponding to HPV types. The chimeric papillomavirus L protein has a higher expression quantity and a better solubility, and can be used for the large-scale production of vaccines.
