Abstract:
Objective:To observe whether the HPV16L1VLP Hela-cell binding-inhibition experiment can assess the immune-protective activities of HPV16L1 antibody in HPV16 prophylactic vaccine or other fields.Methods:C57BL/6 mice were divided into three groups,including pcDNAL1 plasmid,HPV16L1VLP protein,pcDNA3.1 plasmid.Each group of mice was immunized intramuscularly or subcutaneously with certain above antigens,accompanying three times and interval 3 weeks.After 14 days of 3 rd immunization,take blood to make serum for immunochemistry.Results:Hela cell neutralized by the serum IgG of experimental mice can be stained negatively,while the cells of control and non-inoculation groups can be stained positively (brown-yellow color).Conclusion:HPV16LIVLP Hela-cell binding-inhibition assay may be the better way to reflect the neutralizing-protective activities of HPV16L1 antibody in many fields including HPV16 prophylactic vaccine.
