Detection of hepatitis C virus RNA by a combined reverse transcription-polymerase chain reaction assay.
Amplification of RNA by the polymerase chain reaction (PCR) is normally a two-step process requiring separate enzymes and buffer conditions. We describe a combined reverse transcription-PCR (RT-PCR) assay for hepatitis C virus (HCV) RNA amplification in which a single enzyme and buffer condition are used. In this assay, both the RT and PCR steps are carried out with the thermoactive DNA polymer...
متن کاملNested polymerase chain reaction for detection of hepatitis C virus RNA in blood derivatives.
Testing for the presence of hepatitis C virus (HCV) in blood derivatives used in clinical medicine is of enormous importance to ensure the production of safe preparations. So far, no system has been developed for the isolation and detection of hepatitis C virus from blood derivatives. The recently introduced commercial kit for the detection of hepatitis C virus is designed for the isolation and...
متن کاملPrevalence of hepatitis C resulted from blood transfusion in major thalassemia patients in Semnan, Damghan and Garmsar (2002)
Introduction: Hepatitis C is one of the most important liver diseases in the world. The most common cause of hepatitis is blood transfusion. Children with thalassemia who receive frequent blood transfusions are at high risk of hepatitis C virus (HCV) infection. Thus their diagnosis and treatment on them causes reduction of next consequences. Methods: In this descriptive study all the pat...

Detection of hepatitis C virus cDNA sequence by the polymerase chain reaction in hepatocellular carcinoma tissues.
We found the presence of hepatitis C virus (HCV) infection in liver tissues of hepatocellular carcinoma (HCC) patients who had antibodies to HCV but no serological markers for hepatitis B virus infection by the sensitive reverse transcription/polymerase chain reaction (R/PCR) method. The primers used were derived from the non-structural (NS) 3 and/or the structural (C/E) region. Amplified cDNA ...
