    摘要: The present invention is directed toward nucleic-acid based methodologies for the detection of human immunodeficiency virus (HIV) nucleic acids in a sample. A novel HIV-1 isolate, designated MVP5180/91, was isolated from a West African Cameroonian patient with immunodeficiency. Nucleic acid and amino acid sequence comparisons of this isolate, with other HIV-1 strains of subtypes A-E and HIV-2 isolates, demonstrated that this virus shares only limited homology with other known HIV-1 and -2 isolates. However, this virus does display some genetic relatedness to another Cameroonian isolate designated ANT-70. These viruses form the basis for a new HIV-1 group which has been designated subtype O. An immunologically important epitope, corresponding to amino acids 601-623 of the MVP5180/91 transmembrane envelope glycoprotein, was identified. Labeled nucleic acids can be prepared from the nucleotide sequence encoding this region and employed in standard hybridization assays to detect HIV-1 nucleic acids. Alternatively, oligonucleotide primers can also be prepared from this region and employed in polymerase chain reaction (PCR) assays to detect viral-specific nucleic acids.

    摘要: The present invention is directed to an immunochemical method for qualitatively or quantitatively detecting an analyte in which a first and a second binding component are contacted with the analyte, followed by detection of the binding of the binding components to the analyte. According to the invention, both of the binding components are prepared recombinantly in the same host using different vectors (V1 and V2) for expressing fusion proteins, with the first binding component being expressed as a fusion protein F1 in vector V1 and the second binding component being expressed as a fusion protein F2 in vector V2. The novel method, which can also be employed for simultaneously determining several analytes, is more sensitive and specific than prior known methods.
