Quantitative measurement of BCR/abl transcripts using real-time polymerase chain reaction.

BACKGROUND Quantitative real-time polymerase chain reaction (Q-Rt-PCR) is a new tool in the detection and quantification of the BCR/abl fusion transcripts in chronic myelogenous leukemia (CML). This study investigates its specificity, sensitivity and potential clinical usefulness. PATIENTS AND METHODS Parallel analysis of Q-Rt-PCR and the conventional reverse transcription-mediated PCR (RT-PC...

A kinetic model of quantitative real-time polymerase chain reaction.

Real-time polymerase chain reaction (PCR) is one of the most sensitive and accurate methods for quantifying transcript levels especially for those expressed at low abundance. The selective amplification of target DNA over multiple cycles allows its initial concentration to be determined. The amplification rate is a complex interplay of the operating conditions, initial reactant concentrations, ...

Pitfalls of quantitative real-time reverse-transcription polymerase chain reaction.

Polymerase chain reaction (PCR)-based assays can target either DNA (the genome) or RNA (the transcriptome). Targeting the genome generates robust data that are informative and, most importantly, generally applicable. This is because the information contained within the genome is context-independent; i.e., generally, every normal cell contains the same DNA sequence--the same mutations and polymo...

Measurement of Pseudomonas aeruginosa multidrug efflux pumps by quantitative real-time polymerase chain reaction.

Multidrug efflux pumps contribute to multiple antibiotic resistance in Pseudomonas aeruginosa. Pump expression usually has been quantified by Western blotting. Quantitative real-time polymerase chain reaction has been developed to measure mRNA expression for genes of interest. Whether this method correlates with pump protein quantities is unclear. We devised a real-time PCR for mRNA expression ...
