Abstract:
Objective:To study on the target antibody composition,the titer,and immune cross reaction of immunoglobulin products.Methods:ELISA kit for IgG antibody against varicella zoster virus,cytomegalovirus,herpes simplex Ⅰ and Ⅱ type virus,rabies virus,tetanus toxoid and IgG RIA kit specific to hepatitis virus surface antigen were utilized.The antibody titer of 5 kinds of specific immunoglobulin,and the IgG injection for either intramuscular or intravenous preparations was detected.Results:There were higher antibody titer against rabies,HBsAg and tetanus in the immunoglobulin preparations,probably due to the blood donors immunized with correspording vaccination.Compared with the antibody preparations of higher efficacy against cytomegalovicrus dotained by screening,there was a narrow disparity for the titer of the target antibody in the blood IgG preparations.In the population,also widespread existence for infection by varicella zoster virus and herpes simplex Ⅰtype virus,the antibody titer level was lower than those against cytomegalovirus,higher than herpes simplex Ⅱtype virus.Conclusion:All of the 7 kinds target antibody can be detected from the samples of immunoglobulin,antibody titer is related with active and passive immunity,higher titer of against cytomegalovirus can be induced by vaccine of varicella zoster virus,there is noticeable difference for antibody titer level between the intramuscular and intravenous injection immunoglobulin.
