Guidelines

When you review the Gene Expression Plot of a comparative C

T

 study:

• Select the Technical Replicates tab or the Biological Replicates tab to organize and 

view the sample data according to the associated technical replicate group or biological 
replicate group. 

• Change the endogenous control by clicking 

Endo Control

, then selecting a new target.

• Change the reference sample by clicking 

Ref Sample

, then selecting a new sample.

• Omit biological or technical replicates from the analysis. See “Omit Wells using the 

Well Table” on page 200

• Display a subset of the data in the study by selecting one or more rows in the Technical 

Replicates tab or the Biological Replicates tab, then by selecting 

Hide unselected data 

from plot

 in bottom of the Gene Expression Plot. 

Note:

Comparative Ct Example Study.edm does not contain biological replicate groups. 

However, another example study that installed with the 7500 software better 
demonstrates the use of biological groups. You can find the data file for the example 
study on your computer at:

Comparative Ct Study Example (Biological Groups).edm 

Omit Replicates from the Analysis

You can use the Technical Replicates and Biological Replicates tabs of the Gene 
Expression screen to omit technical replicates and biological replicates from the analysis.

To omit a technical or biological replicate:

1.

In the navigation pane, select 

Analysis

 

Gene Expression

.

2.

In the Gene Expression screen, select the 

Technical Replicates

 or 

Biological 

Replicates

 tab according to the type of replicate that you want to omit.

3.

In the replicate table, scroll to the biological or technical replicate of interest, then 
select the check box in the Omit column. 

4.

Click 

Analyze

 when you are finished omitting wells.

IMPORTANT!

You cannot omit 

all

 technical replicates that belong to a reference sample, 

belong to a reference biological group, or serve as the endogenous control for a study.

Note:

You can also omit the technical replicates in the Biological Replicate Details table 

at the bottom of the Biological Replicates tab.
