Notes
Chapter Overview
The 7500 software analyzes the data using the comparative C
T
(∆∆C
T
) quantitation
method. This chapter includes the following sections:
• Section 9.1 explains how to review the analyzed data using several of the analysis
screens and how to publish the data.
• Section 9.2 explains how to perform some troubleshooting steps if you receive
questionable results.
• Section 9.3 explains how to analyze multiple experiments as a study.
