Thermo Scientific Applied Biosystems QuantStudio 7 Pro - Overview of data collection; VeriFlex Zones

Overview of data collection
The instrument collects raw fluorescence data at dierent points during the PCR cycle, depending on
the type of run performed.
When you create a plate file, you can customize the optical filter channels through which the instrument
collects data. You can specify a filter channel set for all PCR thermal protocols and for melt curve
stages.

Typical timing is to collect data at each cycle of a PCR
stage or continuously during a melt stage.

For Presence/Absence and Genotyping analysis,
data collection before the PCR cycle is optional, but
recommended.

(Optional) During the thermal cycling protocol.
Collecting data during the run can confirm
genotyping results by viewing traces in allelic
discrimination plots or viewing genotyping calls at
earlier cycles.
VeriFlex
™
Zones
VeriFlex
™
Z
ones provide independent temperature zones that oer enhanced functionality and precise
control over your real-time PCR runs.
The independent zones are ideal for real-time PCR optimization. They also provide the ability to perform
multiple runs at the same time. Unlike standard gradients which give a sigmoidal temperature curve
across the columns, blocks with VeriFlex
™
Zones help deliver accurate temperatures across every zone.
The QuantStudio
™
6 Pro System has three VeriFlex
™
Zones (Figure 1 on page 19). The QuantStudio
™
7
Pro System has six VeriFlex
™
Zones (Figure 2 on page 19).
Note: VeriFlex
™
Zones are only applicable for the 96-well 0.2-mL block and the 96-well 0.1-mL block.
