Abstract: The present invention relates to nucleic oligomer primers or probes useful for detection of TTV in test samples. Also provided are assays which utilize these primers and probes, as well as test kits which contain these oligomer primers and/or probes. In addition, the present invention encompasses the use of TTV nucleotide sequences as nucleic acid vectors and as markers for determining transmission between individuals as well as the route thereof. Additionally, the present invention encompasses a method of detecting TTV infection prior to xenotransplatation of a tissue or organ.

Abstract: The present invention provides a method for quantitatively detecting the amount of a target nucleic acid sequence which may be present in a test sample. A test sample which may contain a target nucleic acid sequence comprising target sequences X and Y is contacted with two primer sets, the first set being specific for target X and the second set being specific for target Y. The test sample also is contacted at the same time with an internal standard sequence IS, which is substantially derived from a combination of the first and second target sequences, and its corresponding oligonucleotide primers. Haptens are associated with the oligonucleotide primer sets in such a way that amplified target sequence products X and Y are detected by capture on a solid phase to which anti-hapten capture reagents are attached. A signal ratio of (X+Y)/S is determined to quantitate the amount of the target nucleic acid sequence contained in the sample.

Abstract: HGBV-C oligonucleotides from the 5' end of HGBV-C useful for the detection and genotyping of HGBV-C isolates. Also provided are assays which utilize these oligonucleotides.
