Optimization of specimen-handling procedures for accurate quantitation of levels of human immunodeficiency virus RNA in plasma by reverse transcriptase PCR.
Human immunodeficiency virus type 1 (HIV-1) RNA levels in plasma are currently widely used clinically for prognostication and in monitoring antiretroviral therapy. Accurate and reproducible results are critical for patient management. To determine the effects of specimen collection and handling procedures on quantitative measurement of HIV-1 RNA, we compared anticoagulants and sample processing...
متن کاملUltrasensitive reverse transcription-PCR assay for quantitation of human immunodeficiency virus type 1 RNA in plasma.
With the recent introduction of combination therapy, human immunodeficiency virus type 1 (HIV-1) RNA levels in plasma have been dramatically reduced, frequently to below the limit of quantitation (400 copies/ml of plasma) of the AMPLICOR HIV-1 MONITOR Test (Roche Diagnostic Systems). To achieve enhanced sensitivity of the AMPLICOR HIV-1 MONITOR Test, a modified specimen preparation procedure th...

Quantitation of avian RNA tumor virus reverse transcriptase by radioimmunoassay.
A radioimmunoassay was developed that can detect and quantitate 3 ng or more of the avian RNA tumor virus reverse transcriptase. The assay detected no antigenic sites in Rous sarcoma virus alpha virions or in virions of a murine RNA tumor virus. About 70 molecules of reverse transcriptase were found per virion of avian myleloblastosis virus with this assay or with an assay based on antibody inh...
متن کاملHuman Immunodeficiency Virus Reverse Transcriptase
3’-Azido-3’-deoxythymidine 5’4riphosphate (AZTTP) was an efficient substrate for the human immunodeficiency virus 1 reverse transcriptase. It was incorporated into both homopolymer and defined sequence DNA-primed RNA templates and DNA-primed DNA templates. The substrate and inhibitor kinetics of both AZTTP and dTTP were dependent on the template-primer and reaction conditions used. dTMP was inc...
