Abstract (en)

[origin: DE19720914A1] The invention relates to a method for detecting HIV antibodies using an immunoassay. Said method is characterized in that at least one antigen of the env- gene product gp41 of an HIV1-subtype D-isolate and at least one antigen derived from the gp41 of a different HIV1-subtype of group M are used and/or that at least one antigen of the gp41 of an HIV1-subtype E-isolate and at least one antigen derived from the gp41 of a different HIV1-subtype of group M, are used. The invention also relates to antigens and antigen mixtures whose constituents are derived from the gp41 of an HIV1-subtype D-isolate or from the gp41 of the HIV-subtype E-isolate, as well as to their use for detecting HIV antibodies, and to a reagent kit.
