1 Introduction
Safety and installation information
About this chapter This chapter provides information on general safety aspects,
definitions, advice and instructions for unpacking and installing your
instrument. It also gives general information about the instrument
and the control software, system requirements, basic procedures,
control mechanisms and software installation.

1.1 PrimeQ
PrimeQ - the real-time nucleic acid detection system from Techne - has been designed with the
advantage of an open chemistry format that allows the end user full flexibility in the methods and
research they wish to pursue. This is complimented by the user-friendly application software,
Quansoft, for easy setup of experiments and rapid analysis of data.
1.1.1 PrimeQ features
•The white light source and PMT detector provide an impressive excitation range of 470nm
to 650nm and a detection range of 500nm to 710nm.
•Multiplex - multiple wavelengths are detectable per sample using up to four paired excitation
and emission filters housed in individual cartridge systems.
•Wide dynamic range up to at least nine orders of magnitude from starting copy number and
high sensitivity detecting down to 1.0nM fluorescein and single copy templates, depending
upon the assay.
1.1.2 The thermal system
•96-well low-profile microplate format sealed with optical film.
•Temperature-controlled optical heated lid can be set between 100°C and 115°C (or off).
Designed to minimize loss of sample and prevent sample condensation.
•Ramp rates up to 2.2°C/sec.
•Temperature range 4°C to 98°C.
•Block uniformity of less than ±0.25°C.
1.2 Quansoft
Accompanying PrimeQ is Techne’s unique, intuitive wizard-based software, Quansoft. By
employing a series of user-friendly windows accessible from the home page, Quansoft enables
any real-time experiment to be created with ease.
1.2.1 Experiment Editor
By using combinations of plate layouts, thermal cycling programs and analysis parameters the
Quansoft Experiment Editor allows the user easy management of experimental protocols.
1.2.2 Plate Layout Editor
Within a matter of seconds a 96-well microplate can be assigned with blanks, controls, standards,
user-defined samples or unknown samples, all of which are colour-coded for ease of identification.

16
1.2.3 Program Editor
Individual cycle steps, stages or temperature ramps can be added quickly and easily together with
other parameters to build and display the thermal cycling program.
1.2.4 PrimeQ reports
Comprehensive, completely user-customizable reports can be generated from any of the analysis
methods. All result types including graphs can be exported to Microsoft®Word, PowerPoint or
other programs currently used for publication purposes.
1.2.5 Data Analysis
Choose the analysis types and parameters from:
•None
•Baseline
•Quantification
•Dissociation curve
•Plus/minus scoring
•Allelic discrimination
•Multi-read (end point)
1.2.5.1 Quantification
A linearity of at least nine orders of magnitude can be achieved, allowing the user to quantify DNA
down to single copy template or to achieve absolute quantification of 1.0nM fluorescein in a
volume of 20µl.
1.2.5.2 Dissociation analysis
Using the easy-to-program ‘ramp’ function, PrimeQ will perform a dissociation curve that can be
used to determine the temperature at which the DNA strands dissociate. It provides the user with
extra confidence in genotyping experiments and in product verification analysis.
1.2.5.3 Plus/minus scoring
This analysis exploits PrimeQ’s fluorescence technology to determine with ease and accuracy the
presence or absence of a PCR product in any given sample.
1.2.5.4 Allelic discrimination
Users of PrimeQ have the option of this powerful technique capable of detecting single nucleotide
differences (SNPs). It can be used to discriminate between genotypes, mutations and
polymorphisms within or between samples simply by comparing the fluorescence signal obtained
using allele-specific, dye-labelled probes.

17
1.3 Unpacking
When unpacking the unit, check that the following have been removed from the packing:
•This PrimeQ operator guide
•A CD containing an electronic copy of this guide and Quansoft software
•The PrimeQ unit
•A thermal block
•Filter cartridges in box
•Mains lead(s)
•Guarantee card
•Decontamination certificate
•USB cable
Keep the original packaging in case you ever need to return the unit for service or repair. Techne
accepts no responsibility for damage incurred during transportation unless the unit is correctly
packed and transported in its original packaging.
The instrument weighs 25kg (55lb). Take care when lifting – this is best done by two people.
1.4 Warning!
Position the unit so that the mains on/off switch is accessible. If a safety problem
should be encountered, switch off at the power socket and remove the plug from
the supply.
If you are using more than one unit in close proximity to each other, there must be
at least 100mm between the units to allow the cooling air to flow correctly.
1.5 Uses of PrimeQ
PrimeQ has many scientific laboratory applications. Aspects of the PCR process are claimed in
U.S. Patent Nos. 5,475,610 (claims 160-163 and 167) and 6,703,236 (claims 1-6) or
corresponding claims in their non-US counterparts. Use of PrimeQ in such processes is covered
by licenses granted to Techne by Applied Biosystems LLC (except for use in human in vitro
diagnostics).
1.6 Plates
Techne recommends only the type of low-profile plate described in this Guide using reaction
volumes between 15µl and 50µl. Plates must be able to withstand the temperatures you are using
without any danger of deforming to the point where they fracture. Only low-profile plates should be
used. If standard height PCR plates are used, PrimeQ may be damaged and the warranty will be
invalid. Likewise if you put sections of cut-up plate in the block you must balance the plate sections
with empty sealed plate sections or previously used plate sections to balance the pressure on the
heated lid.
During the final cool-down, a ring of condensation may form on the inside walls of the plate wells,
above the liquid level but below the top of the sample block. This is not usually a cause for
concern as the condensation does not form during cycling, due to the action of the heated lid.

18
1.7 Thermal seal
The specification given in this Guide is based on the use of an optical heat seal.
Other types of optical seal may be used; however any seal must be able to
withstand the temperatures you are using without any danger of deforming to the
point where it splits. The user should check the suitability of the seal to be used to
ensure there is minimal sample evaporation.
Where applicable, you should use a heat sealer which seals at a temperature of approximately
170ºC.
Place the plate in the heat sealer base plate, cover it with the seal. Seal the plate for 3-4 seconds;
rotate the plate 180 degrees; seal the plate again for a further 3-4 seconds.
The plate is now correctly sealed and ready for inserting into PrimeQ.
Always be certain that you use the film in the correct way. If you find that you have used the seal
the wrong way up DO NOT PLACE IT IN THE PRIMEQ UNIT as it will damage the heated lid and
this will invalidate the warranty.
Clean the heat sealer before you try to seal another plate.
When using the recommended brand of thermal seal, FHSFILM, and find that it has been applied
the wrong way, the user is advised to send the heat sealer back to their supplier for repair.
Should the user want to attempt in-house repair, the heat sealer should be left to cool and the
heating plate cleaned according to the manufacturer’s instructions.
