Detection of chicken astrovirus by reverse transcriptase-polymerase chain reaction [PDF]
Avian Pathology, 2009 The development of a reverse transcriptase-polymerase chain reaction (RT-PCR) test for detecting chicken astroviruses (CAstV) is described. Primers, which amplified a fragment of 510 base pairs, were located in conserved regions within the ORF 1b (RNA polymerase) gene. The limit of detection of the test was estimated to be approximately 60 viral copies

Generation of non-genomic oligonucleotide tag sequences for RNA template-specific PCR [PDF]
BMC Biotechnology, 2006 Background In order to overcome genomic DNA contamination in transcriptional studies, reverse template-specific polymerase chain reaction, a modification of reverse transcriptase polymerase chain reaction, is used.

West Nile Virus Detection in Urine [PDF]
Emerging Infectious Diseases, 2005 We report West Nile virus (WNV) RNA in urine collected from a patient with encephalitis 8 days after symptom onset. Viral RNA was detected by reverse transcriptase–polymerase chain reaction (RT-PCR).

West Nile Virus Encephalitis in a Barbary Macaque (Macaca sylvanus) [PDF]
Emerging Infectious Diseases, 2004 An aged Barbary ape (Macaca sylvanus) at the Toronto Zoo became infected with naturally acquired West Nile virus (WNV) encephalitis that caused neurologic signs, which, associated with other medical problems, led to euthanasia. The diagnosis was based on

A reverse transcriptase‐polymerase chain reaction assay in the diagnosis of soft tissue sarcomas [PDF]
Cancer, 2000 Many types of sarcomas are characterized by specific chromosomal translocations that result in the production of novel chimeric genes. Detection of these fusion genes could be a sensitive molecular diagnostic assay. However, to the authors' knowledge there have been few systemic comparisons between the current histopathologic diagnosis and the presence
