【Abstract】 The fusion protein from the target antigen gene fragment of the panspecies monoclonal antibody,M2632, has been selected by using different culture temperatures. Westernblot shown that the fusion protein expressed from the target gene fragment can react with the panspecies monoclonal antibody,M2632. It has been confirmed again that the sequence expressed the fusion protein is a target antigen gene fragment of the panspecies monoclonal antibody,M2632. The fusion protein can react with human antiPlasmodium falciparum serum and antiPlasmodium vivax serum. The antifusion protein serum can react with both P. falciparum and P. vivax in IFA test as well. It is suggested that there is a common gene in the target antigen gene fragment of the panspecies monoclonal antibody, M2632, and the protein expressed from the common gene present in antigens of both P. falciparum and P. vivax.更多还原
