The Rotor-Gene Q: Optics
High power light-emitting diodes (LED):
• Highly robust LED technology (Mean time between service visits >50 months)
• Constant and consistent output from run to run (no decay).
• Uniform light-path to well (all wells excited at same intensity), so no optical
normalization and no reference dye (ROX) required.
• Different wavelengths to optimally excite fluorophors at abs max
• LEDs are highly stable with lifetime guarantee (no lasers or lamps to replace)

*OTV disc
The OTV system* uses the chemical properties of three
different thermochromic liquid crystals (TLCs) as an
absolute
temperature reference.
TLCs change from opaque to transparent at a very precise
temperature s (transition point) of 50, 75 and 90oC
The reported value is compared to the known calibrated
value to verify the instrument is within specification. If not
within specification, automatic re-calibration of the Rotor-
Gene can be done at the press of a button.
*patent pending
Easy, routine verification of in-tube temperature in 30 minutes!

QIAgility Liquid Handler Overview & Comparison
QIAgility
QIAgility was specifically developed for PCR setup,
and other liquid handling actions.
Advantages
Easy to use software
Small footprint
Programmed applications
Plug & play
Large Liquid Handlers
Hamiltons, Beckmanns, Tecans and more….
These instruments are real liquid handlers not
specifically developed for PCR setup.
Disadvantages
Complex to programm
Huge instruments – lab space limited
No programmed applications
long installation
Examples: Starlet, Biomek, Freedom Evo 75
19
Sample to Insight
No matter what real-time instrument is used, QIAgility
is compatible
The system is pre-configured to work with all PCR
tube types and all plate formats, including varieties
of 96-well, 384-well and Rotor-Disc
Up to 4 different setups can be performed in parallel
Beside any PCR setup the system can perform
▪ Set-up of quantification standards (dilution
series)
▪ Normalization of sample concentration
▪ Sample pooling
▪ Transfer of samples from one tube format to
another
▪ Plate replication
▪ Restriction digest setup
▪ Cherry picking from archived sample banks
The Hallmark of QIAgility Is Its Versatility
20
Sample to Insight
QIAgility means Time Savings
You have more important things to do…
QIAgility performs complex set-ups faster than can be
done manually
Staff can be attending to other duties while the QIAgility is
running

For many datasets, most of the eigenvalues “lambda” are negligible and can be discarded.
The eigenvalue

Example:
ScreenClust S.W. for HRM and Principal Component Analysis (PCA)
Finding relationship from a large multi-layer sample set is always a challenge. One way to avoid the dimensionality is
by projecting the data onto a lower-dimensional space. It rotates multivariate dataset into a new configuration which
is easier to interpret.
Techniques for dimension reduction:
Principal Component Analysis (PCA) – most effective!
Fisher’s Linear Discriminant
Multi-dimensional Scaling.
Independent Component Analysis.
Sample to Insight
Applications of PCA in Genomics
Purposes…
➢ Simplify data – PCA is the most commonly used dimension reduction technique.
➢ Look at relationships between variables – PCA is useful for finding new, more informative, uncorrelated features.
➢ PCR reduces dimensionality by rejecting low variance features.
➢ Look at patterns of units – i.e. new mutations, targets
➢ Analysis of expression data
➢ Analysis of metabolomics data (Ward et al., 2003)

FAQs I
QuantiNova Multiplex PCR Kit
Is it possible to add the ROX passive reference to the master mix for long-term storage?
If only Applied Biosystems cyclers will be used, QN ROX Reference Dye Solution can be added to the 4x
Master Mix for long-term storage, if desired. Corresponding instructions are given in the HB.
Is the QuantiNova MP PCR mix compatible with partially purified / crude samples?
The kit has been developed for efficient amplification of DNA/cDNA. Typical contaminations from crude
nucleic acid preparations (such as SDS or hemoglobin) will impair the results and will reduce the
sensitivity and specificity of detection.
What is the stability of the QuantiNova MP PCR mix at -20°C, 4°C, and room temperature, respectively?
Our (preliminary) data indicate that the stability will be at least 24 months (-20°C), 12 months (4°C) and
30 days (room temperature).
Is the QuantiNova MP PCR Kit compatible with degenerated primers and probes?
The mix has been developed to provide highest annealing specificity to allow selective target
amplification even if there are many similar target sequences. Therefore, degenerated primers and
probes will not work optimally.

FAQs II
QuantiNova Multiplex PCR Kit
Which reaction volumes can the QuantiNova MP PCR Kits be used with?
Recommended rxn volume: 20 µl (96 well plate), 10 µl (384 well plate)
Successfully tested rxn volume range: 8-25 µl (96 wells), 5-10 µl (384 wells)
What is the maximal number of targets which can be coamplified?
Our „official“ recommendation, as given in the QSP and the HB, are 5 targets. This is the phyisical limit of
most real-time cyclers on the market. However, we have shown, that up to 6 targets can be coamplified
successfully and in an unbiased manner.
Which fluorophor combinations are recommended?
Based on the number of different instruments on the market and fluorophore/quencher combinations offered
by the oligo suppliers, there is no „gold standard“ for the optimal probe combination. Actually each instrument
provider as well as any oligo supplier will provide corresponding information.
On which cyclers has the QuantiNova MP PCR Kit successfully been tested?
Basically almost every instrument from the major real-time PCR instrument suppliers. We did not have
access to AB‘s QuantStudio instruments; however, the technology is comparable to the ViiA7 instrument, on
which the QN MP PCR Kit works very efficiently.

FAQs III
QuantiNova Multiplex PCR Kit
What is the minimal/maximal template input?
Template amounts (gDNA as well as cDNA) up to 800 ng can be used without compromising
quantification.
Undiluted RT reactions can be added to the PCR reaction untill they make up 25% of the total reaction
volume without impairing the quantification results. This has been tested with RT kits from QIAGEN
(QuantiTect, QuantiNova) as well as with RT kits from all major suppliers (Thermo-Fisher/Invitrogen,
Bio-Rad, Roche).
Can the QN MP PCR Kit be combined with contamination removal using UNG (uracil-N-glycosylase)?
Please note that the QN MP PCR Kit neither contains dUTP as one of the nucleotides, nor the enzyme
UNG, both of which are prerequisites for an UNG treatment. However, we have very successfully
tested a modified version of the kit where dTTP has been replaced by dUTP and where UNG has been
added to the master mix. Amplification results were comparable to the „standard version“ and
contamination removal was highly efficient (clearly above 10E6).
If appropriate (revenue dependent), such a customized version can be made.
Various types of probes?
We have exclusively been testing TaqMan probes (both, standard TaqMan probes and MGB-containing
TaqMan probes). We do not expect any problems with other probe technologies such as Hybridization
probes and Molecular Beacons. Minor modifications of the protocol might be necessary (i.e. a 3-step
cycling protocol with separate annealing and extensions steps).
