Applied Biosystems QuantStudio 7 Flex User Manual

In presence/absence experiments, wells that contain IPC blocking agent instead of
sample in the PCR reaction. No amplication should occur in negativ
e control-
blocked IPC wells because the reaction contains no sample and amplication of the
IPC is blocked. Previously called no amplication control (NAC).
In presence/absence experiments, wells that contain IPC template and buer or water
instead of sample. Only the IPC template should amplify in negative control-IPC
wells because the reaction contains no sample. Previously called IPC+.
See “negative control (NC)“ on page 187.
Molecules that are aached to the 3′ end of probes. When the probe is intact, the
nonuorescent quencher (NFQ) prevents the reporter dye from emiing uorescence
signal. Because the NFQ does not uoresce, it produces lower background signals,
resulting in improved precision in quantication. The minor groove binder (MGB)
increases the melting temperature (T
m
) of the probe without increasing its length,
allowing for the design of shorter probes.
Type of calibration in which the software collects data from the normalization
standards, then stores it in a normalization calibration le.
Either the C
t
Avg. of the target gene minus the C
t
Avg. of the endogenous control
(Comparative C
t
experiments), or the Q Avg. of the target divided by the Q Avg. of
the endogenous control (Relative Standard Curve experiments).
The relative standard curve equivalent of the ΔC
t
mean value found in Comparative
C
t
experiments (computed as the geometric mean).
The relative standard curve equivalent of the ΔC
t
SE value found in Comparative C
t
experiments (computed as the geometric standard error of the mean).
Fluorescence signal from the reporter dye normalized to the uorescence signal of the
passive reference dye (usually ROX
™
dye on Thermo Fisher Scientic instruments).
A measurement (such as a C
t
) that deviates signicantly from the measurement of the
other replicates for that same sample.
A dye that produces uorescence signal independent of PCR amplication, and that is
added to each reaction at a constant concentration. Because the passive reference
signal should be consistent across all wells, it is used to normalize the reporter dye
signal to account for non-PCR related uorescence uctuations caused by minor well-
to-well dierences in volume. Normalization to the passive reference signal generally
results in data with noticeably high precision among technical replicates.

number of rows and columns in the grid depends on the sample block that you use.
