1 Introduction

Thank you for your purchase of the Truelab™ Duo Real Time Quantitative micro PCR

Analyzer. The Truelab™ Duo is a revolutionary portable and battery-operated PCR analyzer. It

enables fast, accurate and reliable near-care disease testing. It is easy to use and requires
minimal training.

This is the User Guide for the Truelab™ Duo Real Time Quantitative micro PCR Analyzer. It

provides detailed instructions for the use of all the Truelab™ Duo's available functions, as well as
additional information about its technical specifications, a brief introduction to the concept of PCR
and a glossary.

1.1 Polymerase Chain Reaction (PCR)

The Polymerase Chain Reaction, invented in 1983 by Kary Mullis, is a technique of amplifying

DNA that has found widespread use among professionals and researchers involved with analysis
of nucleic acids due to its high reliability, speed and sensitivity.

Since Deoxyribonucleic Acid (DNA) is unique to each species and individual, it is currently the

most reliable identifier for any living organism, from microbes to humans. Using the PCR method,
even the smallest amounts of DNA can be amplified in order to analyze it. For example, it can be
used to amplify even the smallest trace of an infectious bacterium or virus from a biological
specimen.

The process involves amplifying a specific piece of DNA in a sample using an enzyme called DNA

polymerase and periodic cycling of temperature, which anneal and split strands, respectively.
With each round of annealing and splitting, the amount of nucleic acid doubles leading to an
exponential amplification of the starting trace nucleic acid in a short amount of time.

For instance, a typical PCR reaction that runs for thirty-five cycles, at 100% efficiency, will give you:

35

2 = 34 billion copies

The amplified DNA is then analyzed separately so that it can be identified.

1.2 Real-time PCR

Real-time PCR is a variant of the regular PCR method. It has several advantages over regular

PCR that has made it the PCR method of choice. A Real-time Polymerase Chain Reaction
involves simultaneously amplifying and detecting the target DNA during every cycle, thus
generating accurate information about the presence of the target DNA and its quantity in each
reaction, thus removing the need to analyze the post-PCR product separately.

The Truelab™ Duo Real Time Quantitative micro PCR Analyzer is a Real-time PCR-based

system.

1.3 Understanding Cycle Threshold (Ct Value)

In any Real-time PCR, a positive reaction is detected by the accumulation of the amplicon and

hence of the fluorescence signal. After PCR, each amplification curve is defined by its threshold
cycle (Ct) number. The Ct can thus be defined as the number of cycles required for the
fluorescence signal to cross the threshold (exceeding the background signal of the system). Ct
levels are inversely proportional to the amount of target DNA (or cDNA) in the sample. So lower
the Ct level greater is the amount of target nucleic acids in the sample.

11

True Duolab™

Figure 1 : Model of a real-time PCR amplification plot

Definitions:

1. Baseline: defined as the first few cycles of the PCR reaction where the fluorescent signal is almost
unchanged.

2. Threshold: used to determine the Ct value in a real time quantitative analysis is a value of the
fluorescence that is significantly higher than the baseline, falling in the region of the exponential
amplification.

3. Ct (cycle threshold: is defined as the number of cycles required for the fluorescent signal to cross
the threshold).

Note: Cycle threshold (Ct) is a relative measure of the concentration of the target in the PCR reaction.

Many factors besides the concentration of the target impact the value of the Ct. Therefore Ct
values from PCR reactions run under different conditions or obtained using different PCR
machines and/or reagents cannot and should not be compared.
