Title: Epitope of hepatitis b virus surface antigen and binding molecule specifically binding to same for neutralizing hepatitis b virus
IPC: C12Q1/02
Filed: 2021-10-15
Abstract: PROBLEM TO BE SOLVED: To provide an epitope of hepatitis B virus surface antigen and a binding molecule specifically binding to the same for neutralizing hepatitis B virus. 
     SOLUTION: The present invention relates to an epitope specific to hepatitis B virus surface antigen and a binding molecule binding to the same for neutralizing hepatitis B virus. Since the epitope provided by the present invention is produced by forming a three-dimensional structure and does not comprise an a-determinant, by which escape mutation is induced against an administration of existing vaccines or HBIg, a composition comprising an antibody biding to the epitope or a vaccine composition comprising the epitope has a very low possibility of causing a decrease in efficacy due to escape mutation. Therefore, such an antibody or vaccine composition can be very effectively used in prevention and/or treatment of HBV.
