Curve Example
Experiment
The objective of the relative standard curve example experiment is to compare the
expression levels of the c-myc transcriptional factor (an oncoprotein that activates the
transcription of growth-associated genes) in liver and kidney tissues.
In the relative standard curve example experiment:
• The samples are cDNA prepared from total RNA isolated from liver and kidney tissues.
• The target is human c-myc.
• The endogenous control is human glyceraldehyde-3-phosphate dehydrogenase (GAPDH).
• The reference sample is RNA isolated from kidney tissue.
• One standard curve is set up for c-myc (target). The standard used for the standard
dilution series is a cDNA sample of known quantity prepared from RNA isolated from
lung tissue.
• One standard curve is set up for GAPDH (endogenous control). The standard used for the
standard dilution series is a cDNA sample of known quantity prepared from RNA isolated
from lung tissue.
• The experiment is designed for singleplex PCR, where the target (c-myc) and endogenous
control (GAPDH) assays are performed in separate wells.
• Reactions are set up for 2-step RT-PCR. The High-Capacity cDNA Reverse Transcription
Kit is used for reverse transcription; the TaqMan
®
Universal PCR Master Mix is used for
PCR.
• Primer/probe sets are selected from the Applied Biosystems TaqMan
®
