Comparison of memory B cell polyclonal activation by different phylogeny antigens / 中国免疫学杂志

ABSTRACT

Objective:To characterize the memory B lymphocytes activalion by nonspecific antigen of different phylogeny antigen.Methods:Three groups were immunized by same quantity different antigens,which were ovalbumin,milk and ostrcean extract to intitule A,B,C,respectively,as basic immunity.After one week,across immunity was performed with A,B and C antigen as secondary immunity,the subgroups were divided.Basic antibodies were determined with ELISA before and after secondary immunity.Results:Antibodies after secondary immunity increase 10%～25% than that before secondary immunity in subgroups which antigens were different when basic and secondary immunity.There were significant difference compare with control groups (P
