Objectives To predict and analyze the linear B cell epitopes of the E7 protein from 5common subtypes of HPV(16,18,33,52,and 58)and to determined their prevalence in the Chinese population. Methods The amino acid sequences of the E7 protein from 5high-risk HPV subtypes were acquired from GenBank.ClustalX2 software was used for multiple alignment.The secondary structure of the E7 protein of the different HPV subtypes was predicted using the ExPASY server,SOPMA,and GOR4.Hydrophilicity was predicted using the K...
